-- Information about the crash:
- What I was doing when the application crashed:
1. I removed my Google Hangouts account from Telepathy.
2. I changed status to Offline.
3. I changed status to Online.
4. I clicked on a Telepathy widget in tray and found that Google Hangouts contacts still there.
5. I just clicked on one of contacts when Plasma crashed.
