Application: plasma-discover (5.13.5)

Qt Version: 5.11.1
Frameworks Version: 5.52.0
Operating System: Linux 4.19.2-200.fc28.x86_64 x86_64
Distribution (Platform): Fedora RPMs

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

Messing about, scrolling up and down in plasma discover software updater. Opened updater to search for hex editor using search term "hex". Scrolled up and down while waiting for results. Results loaded in completely. Switched between views that loaded and unloaded the software update view. Lost entry for hex editor I was interested in. Clicked between the application panel and result list; crashed.

The crash does not seem to be reproducible.

-- Backtrace:
Application: Discover (plasma-discover), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
28	  return SYSCALL_CANCEL (nanosleep, requested_time, remaining);
