Application: plasma-discover (5.8.7)

Qt Version: 5.7.1
Frameworks Version: 5.36.0
Operating System: Linux 4.10.0-27-generic x86_64
Distribution: KDE neon LTS User Edition 5.8

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

Discover offered to update packages (namely libinput), I clicked "Update All", Discover asked to remove two packages (libinput dbgsym related), I clicked "No", Discover crashed.

This is a duplicate of parts of bug #376548, which mixes several issues into one. Because of bug #355807, I cannot mark this as a duplicate / attach my information directly.

-- Backtrace:
Application: Discover (plasma-discover), signal: Segmentation fault
