             Bug #: 47760
           Summary: create_and_handle doesn't work if you get two channels
                    back from a request
    Classification: Unclassified
           Product: Telepathy
           Version: git master
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: tp-glib

>From account-channel-request.c:

static void
handle_channels (TpSimpleHandler *handler,
    TpAccount *account,
    TpConnection *connection,
    GList *channels,
    GList *requests_satisfied,
    gint64 user_action_time,
    TpHandleChannelsContext *context,
    gpointer user_data)
{
  TpAccountChannelRequest *self = user_data;
  TpChannel *channel;

  if (G_UNLIKELY (g_list_length (channels) != 1))
    {
      GError error = { TP_ERRORS, TP_ERROR_INVALID_ARGUMENT,
          "We are supposed to handle only one channel" };

      tp_handle_channels_context_fail (context, &error);

But if you create_and_handle a 1-1 Tube channel, sometimes (but not always,
apparently…) you get both a Tube and a Tubes back in the same blob. I'm basing
this on seeing this debug message in my logs and intuition: I haven't actually
looked at the bus traffic and the error message provides no interesting
information. (I will add more details to the error shortly.)

11:02          cassidy | let's just kill Tubes channel
11:02          cassidy | (we have to keep them internally in the code but can
remove them 
                         from the bus)

Are there any other cases where a request returns a plural reply? I think MUC
tubes might be one case.
