libc++abi.dylib: terminating with uncaught exception of type NSException

[gsganden]

When I try to run iMad.py or radcal.py on a Mac (specifically, a mid 2015 Retina MacBook Pro running OS X 10.11.6 "El Capitan"), a Finder window opens, I select a directory that contains two 8-bit three-channel (RGB) geotiffs, and I get the following error.

Any suggestions?

[gsganden]

I have solved the immediate problem described above by changing line 391 of auxil.py from filename = tkFileDialog.Open(filetypes=filetypes,title=title).show() to filename = tkFileDialog.Open(title=title).show() (removing the filetypes argument). I take it that this change is not ideal because it moves the ability to filter by filetype.

[mortcanty]

Yes, not so ideal although also not so important. I can't see the error on 64bit Linux, and I know that there was no problem on my original WIndows 7 development machine, so maybe a bug in OS X/Tkinter?

[gsganden]

That seems right. For the moment I am just going to live with this solution; I do not know when or if I will get the chance to develop something more general.
