sometimes we need to resend/reask auth from transport. may login should do that everytime? (transports are unreliable)
I don't know if this is gajim issue, aim-t issue, xmpppy issue, or... But it only started happening recently (a week or two ago?), and nothing has changed on the server.
When I start gajim (subversion rev 3065), my aim-t icon is greyed, as if I had set my status to "away" (I haven't, my status is "available"). yahoo-t and icq-t are both showing up as "available". If someone sends me an AIM message, they get an auto-response from my client, telling them that I'm available.
If I can provide more useful information, please let me know.
