Bug Description

Not sure if this is really a bug, but still an issue of some kind maybe?

See the screenshot.

Maybe the code could do parsing, like extract the info (ServerClientsCount, ServerServersCount) from the message with regexps?

Sounds like you're connecting to a non-standard/compliant server. Maybe you could paste the traffic log (see trace/debug window).

Sure, here you are. There was something strange in there (Unknown IRC message command '042').

I don't see that particular line in which was in the screenshot though.

Okay, I agree this is probably a deficiency in the message handling routines. It could be the server acting non-compliantly, but the IRC protocol can be rather vague, and this is one of the instances. I've provided a fix anyway, and it should be available on the GitHub repo now.
