-- Information about the crash:
- What I was doing when the application crashed:
Discover was running, I tried to install updates with APT in Konsole, output said synching of ubuntu mirrors was in progress.
Then I closed Discover and it crashed.

The reporter is unsure if this crash is reproducible.

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