Description s1512783 2018-05-23 20:29:49 UTC

Application: plasma-discover (5.12.5)

Qt Version: 5.9.4
Frameworks Version: 5.44.0
Operating System: Linux 4.16.9-200.fc27.x86_64 x86_64
Distribution: "Fedora release 27 (Twenty Seven)"

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

I cannot use Discover at all. It crashes whenever I try to access any of the tabs.

- Custom settings of the application:

I think it may be connected with my attempts to install the Flash plugin RPM from adobe website. It seems like the program started crashing after I tried to use it to install the repo.

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".
