Application: plasmashell (5.5.4)

Qt Version: 5.5.1
Operating System: Linux 4.4.1-1-zen x86_64
Distribution (Platform): Archlinux Packages

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

Trying to add the "Comic Strip" widget to the desktop from the menu to get xkcd; the desktop crashed when releasing the left click. I've successfully added other widgets to the desktop without the shell crashing.

The crash can be reproduced every time.

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