Sentry Crash Report:

Description Heikki 2015-09-29 18:01:19 UTC 
Application: plasmashell (5.4.1)

Qt Version: 5.4.2
Operating System: Linux 4.1.6-3-default x86_64
Distribution: "openSUSE 20150924 (Tumbleweed) (x86_64)"

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

Logged in. plasma crashes, crashes again and either hangs or sometimes crashes the third time and starts working.

This is a duplicate report and propably useless. I just added some debuginfo pagkages but i do not understand much of the crash reports.

The crash can be reproduced every time.

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