Smuxi

Smuxi seems to throw an exception while the smuxi-server is shutting down after sending /shutdown.

This also appears to halt the smuxi-server's shutdown process - when reconnecting, the tabs which had not yet disconnected were still there, and the server hadn't shutdown.

Exception Type:
System.NullReferenceException

Exception Message:
Object reference not set to an instance of an object

Exception StackTrace:
  at System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke (System.Runtime.Remoting.Proxies.RealProxy rp, IMessage msg, System.Exception& exc, System.Object[]& out_args) [0x00000] in <filename unknown>:0 

Exception.ToString():
System.NullReferenceException: Object reference not set to an instance of an object
