This one's not a duplicate of 550750. 550750 requested the ability to hide xchat-gnome by clicking on it in the indicator, which (as Ken pointed out) is not the desired behavior.
This bug requests that when xchat-gnome is closed (via the close button, for example), that it's hidden, just like empathy and rhythmbox do, and just like work is in progress to have evolution do.
