Could not insert media
when receiving an image it crashed with

I have started with an new ID Backup without contents. Where are the duplicates from?
Could you check for me whether 23e5c59e9b3261562d76a334e79f4c943e22cc37 (master) fixed the issue? I found a bug in the de-duplication handling which could have caused this. Otherwise, please share a bit more of the log messages, and if not already done, activate debug logging (CMake: -DOPENMITTSU_DEBUG=On).
this changes it's behaviour to

Query error:

There is nothing after "Query error:"
I will add more debug in a moment
Weird, I pushed a new change that should make it behave, even though I still don't totally understand what is wrong.
If you know how it works, please check the primary key definitions on media in openmittsu's database. SQLiteBrowser (https://sqlitebrowser.org/) can open it, just make sure to start the version with SQLCipher.
The primary key should be on uid and type, not only on uid...
Hmm, strange - copied media to a new media table with PRIMARY KEY(uid,type), but no change

Even with Debug no more details. Sending of images works fine.
Is that with my fix in ff1115f7c05f07803afc4d5ea167d63166e6d540? Wait, does that mean the table did not have the correct key?
Wait, does that mean the table did not have the correct key?
yes, it had PRIMARY KEY(uid)
Is that with my fix in ff1115f?
starts in an neverending loop of something like this
[2021-02-08 15:52:51.235] [main] [error] Detected UUID duplication when inserting file with UUID 509d6aa2-b4e9-44dc-89e8-f670db87e509, size 56505 and file type 2 (if this message appears multiple times, something major is broken!).
The root cause was that for newly created databases, the media table was not created correctly. That this was not discovered earlier is a really, really bad sign... Well, it is fixed now. Opening your database with the new version should automatically fix it (uid is not UNIQUE anymore and the PK is over both columns). Please report back :)
yepp, this works. It changes media table by itself. No more errors in receiving pictures. Only they are not being displayed ;) (sent pictures can be seen in history)
That is actually a different problem - Threema most recently switched to sending images as "files" (like, the internal IDs and techniques used for sending were switched), and openMittsu is not (yet) ready to detect images in files, so it only says: heres a file.
I see, it seems threema itself is in progress. Does openMittu benefit of there strategy to distribute client software as open source development?
Not really, no. But I implemented some necessary changes, the images should now be displayed :)
Not really, no
I thought also about comparing reverse engineered to disclosed code.

That's fine - it is working flawless now. Only in groupchat there is no message about new media at all.
Why oh why do you find every bug there is - not that I am complaining, it's good. Yes, Group file messages were not completely implemented and dropped. I fixed this and some other issues around it. Check out the latest push @ 96bcc73676768343819e8d2736398f672b156db9.
Amazing, you are unbelievable fast in fixing - I didn't planned to be bug reporter, but like to use messenger services on desktop. Okay, I will slow down then. It's quiet good as it is.
No, please keep reporting, this is what keeps the project alive. It was more of a "either nobody bothers to report this issues, or nobody is actually using it" kind of realization.
I see. At the moment I have more feature requests - like showing replies
