Bug 408526

Application: plasma-discover (5.12.8)

Qt Version: 5.9.4
Frameworks Version: 5.45.0
Operating System: Linux 4.12.14-lp150.12.61-default x86_64
Distribution: "openSUSE Leap 15.0"

-- Information about the crash:
- What I was doing when the application crashed:
Just started. Crashed directly.

- Custom settings of the application:
SUSE system update 42.3 to 15.1, clearing caches as adviced, helped for some programs but not Discover, it worked 15.0 for a moment but it's no longer working by now using old user settings directory restored. It works only if using made after upgrade. Overwriting kde config folder taken from other users doesn't help.

It's duplicate - sory about that.

The crash can be reproduced every time.

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