Application: plasmashell (5.9.0) Qt Version: 5.8.0 Frameworks Version: 5.30.0 Operating System: Linux 4.9.7-1-ck-skylake x86_64 Distribution: "Arch Linux" -- Information about the crash: - What I was doing when the application crashed: Just the usual stuff (surfing, writing, etc.) Comming from 5.8.5 the upgrade to 5.9 makes plasmashell crash every few minutes even on idle. Before it was rock solid. When the crash happens my panel is disappearing for a second and is going to reappear then. I use intel modesetting driver and use Arch Linux packages. The crash can be reproduced every time. -- Backtrace: Application: Plasma (plasmashell), signal: Segmentation fault Using host libthread_db library "/usr/lib/libthread_db.so.1".

After uninstalling the following packages: discover kirigami2 kirigami qt5-quickcontrols2 archlinux-appstream-data packagekit-qt5 packagekit plasmashell is back to stable. Though I do not know which package is the culprit
in order to have an useful backtrace it would need full debug symbols, which unfortunately aren't available on Arch
