The code used was lifted directly from your guide for filechooser.
If I change to python 3.6 the same code works.
Finally, after some Google-ing, I found someone with same issue. For me, same crash happening on Windows Server 2012 OS. And, yes, same code is working fine with Python 3.6
I am unclear. Is this issue being looked at or are we supposed to use 3.6?
Apparently nobody found the time/incentive to look into it yet, you can get a more detailed log by running
python main.py -c kivy:log_level:trace
and post it.
I just tested on python3.7 on linux, and i don't get the issue, so it's probably platform-specific.
Sorry, have been meaning to respond to this. The problem is very likely with win32file that is installed by pypiwin32. That is the only thing we import in filechooser selectively on windows that could be responsible https://github.com/kivy/kivy/blob/master/kivy/uix/filechooser.py#L120.
There are two distributions that provide the required modules I think, https://pypi.org/project/pywin32/ and https://pypi.org/project/pypiwin32/. Please take a look with pip freeze to see what you have installed. Try uninstalling and switching to the other to see if that fixes it and report back here with the results. You could also completely uninstalling both, but I'm not sure what else you have installed that may need it.
For reference, on py35 I have pypiwin32==219.
Here is a screenshot of what I have, both and both up to date.

The log doesn't help because these crashes don't get logged and it's a very long log so I'm snipping it.
No I didn't forget the screenshot it is a png attached to the e-mail.. I'll attach again.

Check the issue https://github.com/kivy/kivy/issues/5873 - the image is not shown.
You seem to have both installed. Can you please experiment by uninstalling one or both to see which causes the issue?
Kivy doesn't list this in its dependencies I think so I'm not sure who is responsible for pulling it in. So at best we can just tell people to uninstall the problem one.

I'm using the kivy demo to test this.
Uninstalling pypiwin32 does not fix the problem Uninstalling just pywin32 gets you Errors about win32 module missing but the FileChooser loads directory but you are missing win32 functions.
pywin32 is a dependency of pypiwin32 so both are needed for full functionality.
Uninstalling both and not having either works, but you can no longer have win32 functions.
@bmmcwhirt Are you perchance using 32 bit python? I can't seem to reproduce the issue on 3.7 64 bit. Also, I tested with pypiwin32==223, pywin32==224. Which versions did you test with?

@matham Have been getting this issue since June! You're right I am using 32-bit python! I'll try using 64-bit python
I also have this issue (Python 3.7.2, Kivy 1.11.0.dev):
Is the solution to downgrade to python 3.6?
Here are the versions I have installed:
certifi 2018.11.29 chardet 3.0.4 Cython 0.29.3 Django 2.1.5 docutils 0.14 ffpyplayer 4.1.0 idna 2.8 image 1.5.27 Kivy 1.11.0.dev0 Kivy-examples 1.11.0.dev0 Kivy-Garden 0.1.4 kivy.deps.glew 0.1.10 kivy.deps.gstreamer 0.1.13 kivy.deps.sdl2 0.1.18 numpy 1.16.0 pandas 0.23.4 Pillow 5.4.1 pip 19.0.1 Pygments 2.3.1 pypiwin32 223 pyserial 3.4 python-dateutil 2.7.5 pytz 2018.9 pywin32 224 requests 2.21.0 setuptools 40.6.3 six 1.12.0 urllib3 1.24.1 wheel 0.32.3
I believe switching to 64 bit allowed me to get passed this.

That's strange since I am running 64 bit of python. I have tried running the kivy examples in python 3.7.0 as well, with the same issues.
I can upload whatever is needed to help troubleshoot this issue.
Since switching to 64 bit seemd to have resolved my issue it has been awhile, but I'll test more tonight to verify my claim.

Using 3.7.2 64 bit I no longer have an issue. On Wednesday, January 23, 2019, 8:13:02 AM PST, Dehole [email protected] wrote:

I was able to reproduce it and it seems that it is related to pygame being the Provider for the crashing version.
When running RST_Editor from kivy-examples (and clicking Load):

This question's answer seems to address the problem with .sys files in windows, by creating a filter: https://stackoverflow.com/questions/42393319/kivy-filechooser-doubleclick. Check the section: # filter added. Since windows will throw error on sys files self.fclv = MyFileChooser(filters= [lambda folder, filename: not filename.endswith('.sys')])
Running an edited version of example from the docs, see code below, the code does not crash and operates as expected. Python 3.11.4 Kivy 2.2.1 Windows 11
There are a set of log messages related to accessing hidden system files, these are also listed below. @Julian-O I recommend closing this issue.

@ElliotGarbus: I would like to close this, but I am unsure.
- We are still getting error log messages on what should be a mundane task.
- The reports were very config-dependent, so showing it works on one config isn't sufficient to saw it is closed.
- Some of the proposed causes seem unlikely given the evidence. Some of the proposed work-arounds seem very fragile (timezones? .sys files only?)
@dehole @imalinkowskip @joyZombie @Dannylew12 Are any of you still encountering this with Kivy 2.2.1, and recent versions of the dependencies?
@Julian-O The error messages in the log will only occur if the path in the FileChooser is set to the root (C:) directory in Windows. Set it to any other directory these messages will not be seen. I view this as a non-issue. The workarounds are not required - the system is not crashing.
I'm fine waiting to see if others are still experiencing an issue.
Edit: It might be reasonable to consider if the log messages should be changed to warning (or even info) from error.
@ElliotGarbus: I am taking a different position:
FileChooser needs to work out whether a file is hidden. On Windows it calls win32file.GetFileAttributesExW() which appears to stumble on files that are in use. The stumble is now logged, rather than crashing, which is a step forward.
Python 3.3 introduced os.stat(), which allows access to the hidden flag on Windows. We don't need to support earlier versions of Python. So my proposal:
-
FileChooser's
is_hiddenshould be refactored to use:-
os.stat()andstat.FILE_ATTRIBUTE_HIDDENfor Windows -
os.stat()andstat.UF_HIDDENfor macOS - file starts with a dot for Linux, other platforms (and also for macOS too?)
-
-
FileChooser's platform-dependent imports can then be cleaned up.
