[Telepathy] Clean Disconnect

[tomw]

Hi,

I'm writing an application (telepathy-python) which connects to a jabber
account and which disconnects after a while to then reconnect again. So
far everything works fine, except when reconnecting it seems that some
channels from the previous connection have survived after Disconnect()
on the connection, at least the ConnectionManager.gabble holds the
connection and the subsequent channels, even if the connection does not
appear on the session bus any longer. When reconnecting again and
listening to the "NewChannels" signal immediately gives channels which
should not be there. Their number is increasing after every
connect/disconnect cycle.  Closing the channels explicitly before
disconnecting did not help either. Any idea?

Thanks
