Description thecursedfly 2018-12-04 21:11:42 UTC 
Application: plasma-discover (5.13.5)

Qt Version: 5.11.1
Frameworks Version: 5.52.0
Operating System: Linux 4.19.5-200.fc28.x86_64 x86_64
Distribution (Platform): Fedora RPMs

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

I had opened the "Add source" box where you can add a flatpak repo source path.
Then I clicked to import the flatpak repo file directly from the website instead, by opening the file with Discover. (Browser used to download it was Firefox.)
Then Discover closed unexpectedly.

- Custom settings of the application:

No flatpak repos installed in Discover.

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