Bug 385330

Application: plasmashell (5.10.5)

Qt Version: 5.9.1
Frameworks Version: 5.38.0
Operating System: Linux 4.13.3-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
I was browsing the Application Menu and no other apps was opened. As soon as I hovered over the Development tab, the screen became black and Plasma restarted.
- Custom settings of the application:
I have one panel at the top of the screen, on which there's the Application Menu widget, the icon-only task manager, two instances of the Active Window Control, the system tray and the clock

The crash does not seem to be reproducible.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
