Application: plasmashell (5.4.3) Qt Version: 5.5.1 Operating System: Linux 4.1.13-5-default x86_64 Distribution: "openSUSE Leap 42.1 (x86_64)" -- Information about the crash: I'm frequently getting plasma5 crashes when switching between user sessions. Note: this is using the NVidia binary drivers. I will see if changing the drivers or disabling compositing has any effect. The crash can be reproduced sometimes. -- Backtrace: Application: Plasma (plasmashell), signal: Aborted Using host libthread_db library "/lib64/libthread_db.so.1".
