Alpaca crashes on startup on Debian/KDE

[Haui1112]

Describe the bug
Very recently (also fully updated), the app briefly opens on startup and closes again. If tried persistently, the app opens and briefly works but freezes forever and needs to be closed with kill task. When opened with flatpak run, it displays the following error message:

haui@***:~$ flatpak run com.jeffser.Alpaca

Expected behavior
The app opens and is responsive.

Screenshots

Debugging information

It doesnt get to this. The app does not respond to any clicks.

I too have the problem that it opens and becomes unresponsive on Fedora. After some trying, it starts again, but has forgotten its models. So i need to re-add/"download" them again. And because they are on disk the download is immediate. @Haui1112 can you observe the same?

Hi, thanks for the report, this has been an issue that pops up from time to time.

It's caused by the launching process being done in a different thread than the main one, what I did to fix this is move everything to the main GTK thread except for these:

• Chat loading
• Model loading (available model list / local models)
• Ollama instance loading (when applicable)

I tested the launch process 100 times and it didn't fail at all, of course that doesn't mean is perfect, like I said, it's an issue that pops up from time to time.

I'm still cooking the next release so it might take a couple of days for the fix to reach Flathub.

As for @lightonflux issue, I believe that might be caused by the same threading problem, I've never seen that problem but it might have been fixed with the other stuff.

Good to know. @Jeffser i will report it separately if i encounter it again with the coming version.
