Description Stefan Rücker 2017-02-05 08:26:30 UTC 
Application: plasmashell (5.8.4)

Qt Version: 5.7.1
Frameworks Version: 5.28.0
Operating System: Linux 4.9.0-1-amd64 x86_64
Distribution: Debian GNU/Linux 9.0 (stretch)

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

I've closed several gwenview applications from within the task bar via context-menu -> close. After that I wanted to open K-Menu, open seemed first to be stuck, but after a short "freeze" plasma crashed.

The crash does not seem to be reproducible.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
