Comment 2 Luis Cáceres 2020-12-13 12:35:00 UTC 
Created attachment 134044 [details]
full backtrace

Forgot to mention:

Qt Version: 5.15.2
Frameworks Version: 5.77.0
Windowing System: Wayland
Distribution: Gentoo

The crash happens randomly when changing tracks.

Also, I literally just got another backtrace. Crash happens in a different place but seems to be related to the TrackMetadataModel. Attached the full backtrace.

elisa (20.12.0) using Qt 5.15.2

Elisa sometimes crashes at the end of the song. There doesn't seem to be any specific song or situation that would reliably reproduce this situation.

Comment 4 tneo 2021-01-14 14:09:40 UTC 
Same happens with TumbleWeed packages. I have not run it through terminal to get a traceback.
Comment 5 Matthieu Gallien 2021-01-22 08:51:22 UTC 
Thanks for the report and the detailed backtraces.

I can confirm it and will work on a fix as soon as possible.

Sorry for that and the delay
