Sentry Crash Report:

Description lafferx 2016-01-27 20:53:01 UTC 
Application: plasmashell (5.5.3)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-1-default x86_64
Distribution: "openSUSE Tumbleweed (20160121) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
I unlocked the desktop (by entering login credentials) and got 2 messages that Plasma had crashed. I can not say for sure that unlocking process ITSELF caused the crash (perhaps it is caused by some background process that starts when the desktop is locked), but every time I see these 2 crash messages, it is after I unlock the desktop.

The crash can be reproduced sometimes.

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