-- Information about the crash:
- What I was doing when the application crashed:
1. Open plasma-discover from a terminal
2. Search for "win7 volume" (previously installed in a separate Discover
instance)
3. Click on the installed result
4. Click "Remove"
5. Discover crashes as shown in the stack trace
The reporter is unsure if this crash is reproducible.
