Description DarthZiplock 2026-01-13 20:38:16 UTC

SUMMARY
I use Gmail installed as a PWA via Brave flatpak to check my email. After the KDE Frameworks 6.22.0 update, plasmashell will sometimes crash when a new email notification is received.

STEPS TO REPRODUCE
1. Install gmail as PWA via Brave flatpak and enable notifications
2. Receive a new email+notification
3. Plasmashell *sometimes* crashes. Not all the time, but when it does, it's immediate as soon as the notification is played

OBSERVED RESULT
Plasmashell *sometimes* crashes. Not all the time, but when it does, it's immediate as soon as the notification is played

EXPECTED RESULT
Plasmashell should not crash

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Fedora 43
KDE Plasma Version: 6.5.4
KDE Frameworks Version: 6.22.0
Qt Version: 6.10.1

ADDITIONAL INFORMATION
The backtrace instructions went over my head, but I've submitted crash reports every time it's happened over the last week.

Thanks for the crash report. As the message at the top of the summary says, if something crashed, we need a backtrace of it so we can figure out what's going on. Without a backtrace, unfortunately, the developers don't have the information they need to fix the code.

Can you please attach a backtrace of the crash using the coredumpctl command-line program, as detailed in https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl ?

Another option is to use the Crashed Process Viewer, which should be in your application menu. 
1. Double click the most recent crash for plasmashell
2. Click Copy to Clipboard and paste the information into a new text file
3. Save the file and attach it to this report

Thanks.

I was able to get the backtrace via Crashed Process Viewer per your instructions, hopefully it helps!
