Bug 455044

SUMMARY
NeoChat crashes for me consistently, trying to leave an just created room


STEPS TO REPRODUCE
1. Open NeoChat
2. Create a room (I just used "qwer" as both name and topic)
3. Click on the room to open it in the main window
4. Click on the settings -> leave room

OBSERVED RESULT
NeoChat leaves the room and then crashes

NeoChat shouldnt crash after leaving the room
