How I reproduce:
- Have 2 jabber account in Empathy
- Send a file to yourself on another account with Empathy
- When the incoming FT offer arrives (the FT icon blinks), do not click
- Start d-feet, check the FT channel object path and bus name
- Call AcceptFile(0, 0, "", 0) manually on D-Bus. I do that with my Tomboy
plugin which does not work yet.

It is possible that I copied the wrong object path when I copy/pasted from
d-feet, and used the outgoing channel instead of the incoming channel, I am not
sure.

The code is:
  if (g_stat (path, &buf) == 0)
    {
      /* The file is not supposed to exist */
      DEBUG ("file %s already exists", path);
      g_assert_not_reached ();
    }

And it crashed.

dbus-monitor shows:
method call sender=:1.2412 ->
dest=org.freedesktop.Telepathy.Connection.gabble.jabber.alban_2ecrequy_40collabora_2eco_2euk_2fchocolatine

member=AcceptFile
   uint32 0
   uint32 0
   variant       string ""
   uint64 0

And my Tomboy code is:
  IFTChannel FTChannel = Bus.Session.GetObject<IFTChannel>
("org.freedesktop.Telepathy.Connection.gabble.jabber.alban_2ecrequy_40collabora_2eco_2euk_2fchocolatine",
new ObjectPath
("/org/freedesktop/Telepathy/Connection/gabble/jabber/alban_2ecrequy_40collabora_2eco_2euk_2fchocolatine/FileTransferChannel/0xa20f000"));
  string DummyVariant = "";
  object Address = FTChannel.AcceptFile (0, 0, DummyVariant, 0);
