Should post to gtk-list or gnome-devel-list rather than this list.

My theory is that because the text view does a lot of its own DND
handling, you are basically creating a situation where on drag_drop 
gtk_drag_get_data() is called twice requesting two bits of data, 
once by textview and once by the drag_dest_set stuff you set up. 
Or something along those lines.

You really need to override/replace all or many of the default DND
handlers in the text view, at least when the drag involves the targets
you want to change behavior of. You could do that using e.g.
g_signal_stop_emission_by_name() to kill callbacks other than your
own.
