Outgoing messages marked as undelivered, although they are delivered.
Bug description
I have gajim and the other person uses Tkabber 0.11.1 (Tcl/Tk 8.5.10) In gajim my messages have that yellow sign with '!', although the person sees my messages.
Software versions
Ubuntu 11.04 64 bit, I've tried gajim 0.14.1 and nightly .deb.
