I think the Away icon sells it :)

There seems to be a bug that if someone in a conversation sends you a message after midnight, the messages don't scroll up like they normally should.

I've tried looking for the icons, no luck. Not sure what happened to them.

Sorry for being so misleading :P the name has been changed.

Ha, maybe someone with a SDK could do it? :P I'll make the name less misleading if it's a problem.
