Sebastian Stein <seb....@hpfsc.de> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |seb....@hpfsc.de --- Comment #2 from Sebastian Stein <seb....@hpfsc.de> --- Since upgrading to Kubuntu 16.04, my plasmashell also crashes. The window bar disappears for a few seconds and restarts. To me, it looks like this happens when I try to select another window by mouse click and the preview of the window gets shown. I can reproduce the bug by just hovering with the mouse over an entry in the window bar. Application: Plasma (plasmashell), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
