Bug ID: 458852 Summary: Plasmashell crashes on KDE desktop start in X11 and cannot be fixed Product: plasmashell Version: 5.24.6 Platform: Ubuntu Packages OS: Linux Status: REPORTED Keywords: drkonqi Severity: crash Priority: NOR Component: general Assignee: plasma-b...@kde.org Reporter: pmuhl1...@gmail.com CC: k...@davidedmundson.co.uk Target Milestone: 1.0 Application: plasmashell (5.24.6) Qt Version: 5.15.3 Frameworks Version: 5.92.0 Operating System: Linux 5.15.0-47-generic x86_64 Windowing System: X11 Distribution: Ubuntu 22.04.1 LTS DrKonqi: 5.24.5 [KCrashBackend] -- Information about the crash: Please note: I'd be willing to try to recreate the bug with debug symbols, but I just cannot find the debug packages for the list of files mentioned by this crash handler. - What I was doing when the application crashed: Just before the crash recorded here, I was using Gnome, switched user, and tried to start KDE desktop. It comes up and opens applications, but the background is black and the panels are missing. More generally, after a system reboot a couple days ago, every time I go into KDE I see what I'm seeing now--no panels, black background. I don't typically get asked to do a bug report. - Unusual behavior I noticed: I upgraded to 22.04 a couple weeks ago from 20.04, where I had no problems with KDE panels. In 22.04, I noticed the panels were unstable. They and the background would disappear after suspend or sometimes while I was using the desktop. I used 'kstart5 plasmashell' to resume the panels and background, which worked. I am using X11. But a few days ago, I rebooted to find that the panels and background were missing, which had not happened before. When I tried to use variations of 'kquitapp5 plasmashell && kstart5 plasmashell' to activate the panels and background to no effect. Multiple reboots made no difference. I reinstalled all the software related to plasma I could find, also to no effect. I did upgrade a couple packages before the reboot after which KDE stopped functioning properly. I could be wrong, but I think those packages were: kde-config-sddm and bluedevil. - Custom settings of the application: I moved the panels around, resized them, and added a few widgets (weather widget, widget to show all open windows, widget to minimize all). Besides the weather widget, I don't think I'm using anything besides what I normally have for years. The weather widget worked for a number of days before my KDE stopped functioning properly. The crash can be reproduced every time. -- Backtrace: Application: Plasma (plasmashell), signal: Segmentation fault [KCrash Handler] #4 0x00007f3ba65b2074 in Plasma::Applet::immutability() const () from /lib/x86_64-linux-gnu/libKF5Plasma.so.5 #5 0x00007f3ba65b214d in Plasma::Applet::destroy() () from /lib/x86_64-linux-gnu/libKF5Plasma.so.5 #6 0x00007f3b9cc2df29 in ??
