           Summary: Emit StreamError(..., Codec_Negotiation_Failed, ..) in
                    more cases
           Product: Telepathy
           Version: unspecified
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: gabble
        AssignedTo: telepathy-bugs at lists.freedesktop.org

If you try to add video to an existing audio call, but I don't support any of
the codecs you propose, TpFs calls Error(Codec_Negotiation_Failed, ...) on the
stream, and my Gabble correctly emits StreamError(...,
Codec_Negotiation_Failed, ...) for that stream. However, my Gabble just sends
you a content-remove with no reason.

Firstly, it should send a content-reject.

Secondly, as per
<http://mail.jabber.org/pipermail/jingle/2009-November/001112.html> it should
include <reason><failed-application/></reason> in the content-reject.

Thirdly, it should also include <failed-application/> when terminating a
session because none of the codecs in the initiate were supported.

Fourthly, it should react to session-terminate with <failed-application/> by
emitting StreamError(..., Codec_Negotiation_Failed, ...) for each stream before
ending the call.

This would allow the UI to tell the user what happened in more cases than it
currently can.
