gabble log

Hi,
>From what I understood, calling EnsureChannel will create a channel for us, and
if the channel already exists, it will give us the channel with yours=false.
however, this does not seem to work. I've been struggling with this for a
couple of days before realizing the bug comes from gabble.
If I call EnsureChannel (on the Account), when a channel already exists, I will
never get an answer from gabble.
I'm attaching a log from gabble taken with  GABBLE_DEBUG=all WOCKY_DEBUG=all.
What I do is connect my account in empathy, then join a MUC in empathy, then I
run teamgeist which tries to join the MUC by calling EnsureChannel. The request
is never answered.
Sometimes (didn't seem to happen in this particular case, even though I waited
about 10 minutes), I get after a long timeout the signal Failed on the
ChannelRequest with the message (the 'error' argument being empty) : 
"Did not receive a reply. Possible causes include: the remote application did
not send a reply, the message bus security policy blocked the reply, the reply
timeout expired, or the network connection was broken."

By the way, since I'm doing a lot of testing by launching
teamgeist/ctrl-c/launch/ctrl-c/etc.. I can sometimes reproduce this bug without
even opening the MUC in empathy, and with dbus-monitor I see the StatsChanged
signal with ChannelCount reporting many channels (text or dbustube), which seem
to mean that sometimes a channel is not destroyed even if the process that
requested it got killed... so there's a channel leak here, and it prevents me
from continuing without killing gabble.
