Disconnects aren't handled properly
Voluntarily and unvoluntarily disconnects are not handled properly by Quassel and result in a crash.
[WARNING] QThread: Destroyed while thread is still running
The problem occurs when...
- connecting to an IRC-Server and the registration process cannot be properly finished (either user or
nick fails, without beeing able to recover from that error)
- the connection is interrupted due to network loss
- a /quit command is issued
- the user is killed by an oper, server, or service
