Application: plasmashell (5.5.5) Qt Version: 5.5.1 Operating System: Linux 4.1.34-33-default x86_64 Distribution: "openSUSE Leap 42.1 (x86_64)" -- Information about the crash: It usually happpens when I start an application (usually by clicking an icon on my desktop) or just killing a windows with an appication (like midnight-commander) by clicking on the X in the upper-right angle. BUT: I can not reliably reproduce a crush: looks like it happens not on every kill/create event but rather once per few (say 5 or even 10) such events. The crash can be reproduced sometimes. -- Backtrace: Application: Plasma (plasmashell), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".
