Application: plasma-discover (5.14.0)

Qt Version: 5.11.1
Frameworks Version: 5.51.0
Operating System: Linux 4.15.0-36-generic x86_64
Distribution: KDE neon User Edition 5.14

-- Information about the crash:
- What I was doing when the application crashed:
I tried installing Runescape with the script from their official site, it failed to update the repo.
Every time i tried to update through discover or terminal it failed, so i removed the runescape.list in  /etc/apt/sources.list.d.
Updated repos and upgraded through apt in terminal and everything went fine.
Meanwhile Discover update prompt screen was opened all that time, and it detected that my system was updated, it didn't ask me to update anymore.
I clicked on Applications and Discover crashed.

-- Backtrace:
Application: Discover (plasma-discover), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
