Application: plasmashell (5.10.3) Qt Version: 5.9.1 Frameworks Version: 5.36.0 Operating System: Linux 4.9.37-1-lts x86_64 Distribution (Platform): Archlinux Packages -- Information about the crash: - What I was doing when the application crashed: don't know specifically. - Unusual behavior I noticed: plasmashell eats up all my cpu. when it starts while logging in, it constantly gets higher. then when I kill plasmashell. the cpu usage goes down to almost zero. when I then normally start plasmashell again by CRTL+F2 usually the high cpu usage doesn't come back. The crash can be reproduced sometimes. -- Backtrace: Application: Plasma (plasmashell), signal: Segmentation fault Using host libthread_db library "/usr/lib/libthread_db.so.1".
