Bug 372313

Application: plasmashell (5.8.3)

Qt Version: 5.7.0
Frameworks Version: 5.27.0
Operating System: Linux 4.4.30-1-MANJARO x86_64
Distribution: "Manjaro Linux"

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

On my Manjaro Linux (based on Arch):

1. Drag the comic strip widget from the widgets-area to the Desktop
2. click on 'configure' in the widget area
3. click on "Get new comics..."
 -> Plasmashell crashes (and instantly restarts)


I already had a bug described in https://bugs.kde.org/show_bug.cgi?id=357222 (My Bug Report has been marked as duplicate, Bug 369172).
After updating (with the official Manjaro updates), i tried it and I was able to do the above steps.
The former bug describes a Crash right after the first step.

The crash can be reproduced every time.

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