Description Tony 2017-12-12 08:29:53 UTC 
Application: plasmashell (5.11.90)

Qt Version: 5.10.0
Frameworks Version: 5.42.0
Operating System: Linux 4.14.3-1-default x86_64
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:
Tried to download new widgets using "Download New Plasma Widgets" option from the widget browser.
The 1st time i click on it, sometimes noticed a window opening and closing really fast others times it does nothing. Trying out again will always crash plasma.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
