Bug 387306

Application: plasmashell (5.11.3)

Qt Version: 5.9.3
Frameworks Version: 5.40.0
Operating System: Linux 4.13.12-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
Just finished updating via pacman. Closed out Terminal application and went to shut down the system. Clicked on the menu button and KDE locked up and crashed.

- Unusual behavior I noticed:
KDE did not respond when I clicked on the menu button. I tried clicking it a few times, but still no response. Desktop icons remained in place, but bottom menu bar crashed and recovered.

The crash does not seem to be reproducible.

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