-- Information about the crash:
Sometimes, Plasma just crashes at random times. Desktop wallpaper gets black and all panes disappear. Shortly after, everything works as usual and the Crash Handler appears. 

I have had this issue 3 times now (since I installed Debian 12 with KDE Plasma 5 days ago), so I decided to just report it. I don't really know why it happens and what exactly causes it, and it isn't really a problem for me, but maybe the logs could be helpful :)

The first two times it crashed at completely random times while I wasn't doing anything except browsing the web or similar.
The third time it happend directly after waking the system from sleep.

The crash can be reproduced sometimes.

Note: I only switched to Debian testing yesterday. The first two crashes happened when I was on Debian 12 and the third was on Debain testing.

Comment 3 Mario Ebenhofer 2023-07-14 17:16:49 UTC

The crash just happened again, and like a few times before, it's saying that the crash information is not useful. 
It says that some packages are missing, that should be installed...

The packages containing debug information for the following application and libraries are missing:

/usr/bin/plasmashell
/lib/x86_64-linux-gnu/libQt5Core.so.5
/lib/x86_64-linux-gnu/libQt5Quick.so.5

I just read in Bug 414823 that this issue is fixed in QT6... So I can just ignore it and when Plasma 6 releases (and I install it), that crashes will just stop happening, right?

That is correct! Thanks for your patience.
