           Summary: Doesn't clean up properly if CM dies.
           Product: Telepathy
           Version: git master
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: logger
        AssignedTo: telepathy-bugs at lists.freedesktop.org
        ReportedBy: will.thompson at collabora.co.uk
         QAContact: telepathy-bugs at lists.freedesktop.org


I found that sometimes, opening conversations to particular contacts would wait
for MC's call to tpl's ObserveChannels implementation to time out before the
channel could be dispatched. And, inevitably, those conversations weren't
logged.

I tracked this down to a pair of issues:

• tpl only forgets about a channel if it emits Closed(), which doesn't happen
if I kill Gabble. If the same object path is re-used the next time I connect
(without restarting tpl) then it just ignores the channel.
• If tpl chooses not to observe any channels from the list passed to
ObserveChannels(), it never returns from the method. This is the classic
expecting-at-least-one-async-operation-when-actually-there-may-be-none bug.

Patches to follow.
