Qt Version: 5.5.1
Operating System: Linux 4.1.34-33-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
I had locked the account and was working in another one. When I returned Plasma crashedwith the message "We are sorry, Plasma closed unexpectedly"
This does not happen every time. It seems to go through phases of happening every time then not happening at all.

The crash can be reproduced sometimes.

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