Description Michal Papis 2016-05-22 13:46:38 UTC

Application: plasmashell (5.6.4)

Qt Version: 5.6.0
Frameworks Version: 5.22.0
Operating System: Linux 4.5.4-1-default x86_64
Distribution: "openSUSE Tumbleweed (20160422) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Disabled Bluetooth in the applet from system tray

- Unusual behavior I noticed:
The whole bar gets very slow, it does not respond to clicks, it does not allow network after sleep, bluetooth gets disconected, clicking anything freezes the interface for some time, the applets stay visible for this time, only after they disapear everything starts working again.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
