When someone invites me to a muc room, the trayicon turns into the "pending message" state (and says I have 1 pending message) ; when I click, I get the invitation and can answer it.
And the trayicon still is in the "pending message" state (and says I have 1 pending message). I can't hide/show the roster window by a left click anymore (right click still work).
When I quit, gajim tells me I still have a pending message...
My guess is that "answering" an invitation doesn't trigger the same things as "answering" a message. Should not be too hard to fix.
This is on ubuntu dapper.
