Description

Connecting to smuxi-server this morning seems to be triggering a null reference exception on the server. That in turn then causes the server to reconnect to the IRC server, after which it again crashed, over and over again until I killed it.

Nice catch, you found a parser bug in the IRC lib. Though I will need the line that triggered it, with smuxi-server -d or smuxi-frontend-gnome -d it should log the that was received before the crash.

Could it be that you connect Smuxi to a bouncer or some other form of unusual IRC server? At least that is what likes to bend the IRC RFC or even violates it which the IRC lib is not so forgiveful about. Whatever the issue is, the IRC lib needs to cope with it in a non-exception way :-)

OK, I spotted a potential NullReferenceException in the code for group chats without users inside (like disabled chat after kick or connection loss). I will fix this one and this might solve the issue already for you.
