When hibernating with Gaim active, and then resuming later, Gaim looks and behaves as if it has active connections and is connected to the network - however, it may just display how it looked when hibernate was invoked.
Eventually, it will come around and update its status by itself, but I've seen this take up to about 20 minutes for an account before it notices that it isn't still connected and refreshes. During this time, there is no indication that the user is not in fact connected and available, unless a message is attempted. Very undiscoverable.
The only workaround (apart from closing and starting Gaim) is to manually set status to Offline, then back to Available/Away etc.
Solution: The system should notify Gaim that it should refresh its status, in some appropriate way. Perhaps upstart could simply tell Gaim to refresh all accounts via dbus or something like that, or maybe a small, active-by-default plugin could be added.
Posting bug here in the first place, because best solution for Ubuntu may be upstart-specific.
I triaged it and it appears fixed. I am instantly connected when restored from hibernation. Read more about it here: http://
