Application: plasmashell (5.6.90) Qt Version: 5.5.1 Frameworks Version: 5.20.0 Operating System: Linux 4.2.0-30-generic x86_64 Distribution: KDE neon on 15.10 -- Information about the crash: - What I was doing when the application crashed: After logging in plasmashell start loading until the bottom panel starts rendering. Then it crashed. I restarted plasmashell several times using krunner and konsole and the same behaviour occured each and every time. The same thing happened even if I restart lightdm or after doing a full pc restart. To fix the issue I renamed .config folder and restarted the system and the problem seems to be fixed. The crash can be reproduced every time. -- Backtrace: Application: Plasma (plasmashell), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

This I hope will be fixed in 5.7.2. (to be released tomorrow iirc) Can you update the version - and specify the plasma version you use (not the plasma framework, but plasma shell)? And, can you re-test when you update to 5.7.2 to see whether this is still an issue?
I am currently at 5.7.1 as soon as I update I will try to reproduce and let you know
