--- Comment #7 from Harald Sitter <sit...@kde.org> ---
nullptr implosion.
I have seen this triggered thusly:
- open discover
- start update
- click on a deb or somesuch in dolphin
- discover gets focused with package install view
- click install
- wait a bit
- click on update section in the left hand side pane
- crash
better trace:
Application: Discover (plasma-discover), signal: Segmentation fault
