Bug 372031

Application: plasmashell (5.6.5)

Qt Version: 5.5.1
Frameworks Version: 5.23.0
Operating System: Linux 4.4.0-45-generic x86_64
Distribution: Linux Mint 18 Sarah

-- Information about the crash:
- What I was doing when the application crashed:
1. I have opened Kickoff App Launcher
2. Typed "pulse" to open volume settings.
3. Volume settings has opened
4. Plasma has crashed
- Unusual behavior I noticed:
When I have opened volume settings, only first tab has opened - "playback" (sorry, don't know how it properly looks in english version), others hasn't ("recording", "input devices", "output devices", "configuration")

The crash does not seem to be reproducible.

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