Description cervanz 2018-06-11 09:52:23 UTC

Application: plasma-discover (5.12.5)

Qt Version: 5.11.0
Frameworks Version: 5.46.0
Operating System: Linux 4.16.13-2-ARCH x86_64
Distribution (Platform): Archlinux Packages

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

opened up discover and clicked on application addons, i saw multiple errors stating "parley.knscr: error initializing provider" then it crashes. this problem is repeatable and happens every time i open discover. Now the discover app refuses to load and crashes immediately with no error.

-- Backtrace:
Application: Discover (plasma-discover), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
