Description Petr Břeň 2015-09-08 12:09:30 UTC 
Application: plasmashell (5.3.2)

Qt Version: 5.5.0
Operating System: Linux 4.1.6-200.fc22.x86_64 x86_64
Distribution: "Fedora release 22 (Twenty Two)"

-- Information about the crash:
- What I was doing when the application crashed:

I was updating the system (i have fedora) using the green applet in the systray. After that, plasma crashes. It restarts itselft, no data is lost and the update seems to be successful. It doesn't happen after every upgrade but lately it's been doing it quite often.

The crash can be reproduced sometimes.

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