           Summary: [0.9] file transfer featureneg fails with "attempts to
                    spoof an IQ reply"
           Product: Telepathy
           Version: unspecified
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: gabble
        AssignedTo: telepathy-bugs at lists.freedesktop.org
        ReportedBy: simon.mcvittie at collabora.co.uk


When I try to send a file from Gabble 0.9.2-1 (and Empathy) in Debian to Pidgin
2.5.4 in Windows, each participant's UI claims to be waiting for the other, and
I get this Gabble debug log (slightly anonymized, but the JID in googlemail.com
is the recipient and the JID in pseudorandom.co.uk is me):

  </si>
</iq>

It looks as though either Wocky or the code in Gabble that interacts with Wocky
is failing to match the sent message to the reply, perhaps because it has added
an ID to the <si> and (wrongly?) expects the reply to have that ID, rather than
the ID of the <iq>.

My status at the time was hidden, in case that's significant.
