Description Konstantin 2024-07-10 23:36:56 UTC

Application: plasmashell (5.27.5)

Qt Version: 5.15.8
Frameworks Version: 5.103.0
Operating System: Linux 6.9.7-custom-for-server x86_64
Windowing System: X11
Distribution: Debian GNU/Linux 12 (bookworm)
DrKonqi: 5.27.5 [CoredumpBackend]

-- Information about the crash:
Plasma crashed after I unlocked the computer and closed the pop-up notification about an incoming call from KDE Connect that had happened some time ago.
A few seconds after the Plasma crash, the desktop panels and almost all windows were restored.
I noticed that the previously opened window of the Winpower Java application was closed after the Plasma crash and was not restored, unlike other windows.
Debian 12 with custom kernel 6.9.7. 
Similar behavior has been observed before with previous versions of custom kernels, but several months ago.

The reporter is unsure if this crash is reproducible.

Comment 3 Akseli Lahtinen 2024-07-11 10:56:56 UTC

Ah sorry, I was looking at wrong bug report. Anyhow, thank you for your bug report.

Debian advises users to not submit bugs upstream (https://www.debian.org/Bugs/Reporting), as this version of the KDE software is out of support from KDE, and so it's possible that the bug exists only in Debian at this point.
Could you report the bug to Debian using the report bug utility (https://packages.debian.org/stable/utils/reportbug)? If necessary, the maintainer of the package will forward the bug upstream.

Thanks for understanding!

Hello. Thanks for your reply.
I created a Debian bug report: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1076140.
