I think the problem is elsewhere.

The dnd code has a flaw in it, it generates dnd-events (lisp events) for wrong 
ClientMessages (X events), in this case a _MOTIF_WM_MESSAGES ClientMessage.

These non-real dnd events gets filtered out in x-dnd-handle-drag-n-drop-event 
(x-dnd.el) so they have no impact normally.  I didn't realize they could 
interfere in other ways.  I'll rework the generation of dnd lisp events so 
they are generated for genuine X dnd events only.
