-- Information about the crash:
- What I was doing when the application crashed:
I dragged a plasmoid from one monitor to the next. Thereby the content of the plasmoid disappears and plasma crashes.

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
