           Summary: Sending queue getting stuck because of vCard stanza
                    not being sent
           Product: Telepathy
           Version: unspecified
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: major
          Priority: medium
         Component: gabble
        AssignedTo: telepathy-bugs at lists.freedesktop.org
        ReportedBy: guillaume.desmottes at collabora.co.uk
         QAContact: telepathy-bugs at lists.freedesktop.org


Marc is experiencing a pretty nasty issue with Gabble. It can't send any
message to contacts.

After a lot of digging, I discovered that Gabble tried to send a stanza
containing his vcard and this sending operation is never terminated
(wocky_xmpp_connection_write_cb is never called). As a result, the Porter
continues queueing any other outgoing stanzas and so he can't send any message.

The stanza being sent weight 16518 bytes which is big but not insane either. I
tried setting the same avatar to a gmail test account (I disabled Empathy's
avatar resizing code to make sure to send the full sized avatar) and didn't
observe any issue.

I have full logs and tcpdump available if needed.
