-- Information about the crash:
- What I was doing when the application crashed: I was watching youtube fullscreen on firefox while installing spotify-snap through the app store.

- Unusual behavior I noticed: The system became unresponsive for a few seconds, Kwid warned me about the crash, but spotify installed regularly

The reporter is unsure if this crash is reproducible.

-- Backtrace:
