-- Information about the crash:
- What I was doing when the application crashed:
I removed two weather widgets after one widget's removed notification cleared, then screen became black and plasmashell crashed.

The reporter is unsure if this crash is reproducible.

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