Application: plasmashell (5.16.0)

Qt Version: 5.12.3
Frameworks Version: 5.58.0
Operating System: Linux 5.1.7-1-default x86_64
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:
I used the "jump to strip..." menu entry of the Comic Strip widget
- Custom settings of the application:
2 Comic Strip widgets active, one with XKCD strips and one with Dilbert.
FWIW, other widgets on the desktop:
* folder view
* thermal monitor
* hard disk I/O monitor
* CPU load monitor
* Memory status

The crash can be reproduced every time.

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