Ignore my previous guess. I got my GtkTreeView -> GtkTextView drag/drop 
working.

Check the GtkTargetEntry parameter you pass to the gtk_drag_set_source 
and gtk_drag_set_dest functions. If they don't match, it wont work.

I found that to drag from a GtkTreeView to a GtkTextView I had to set 
the target to:
static const GtkTargetEntry targetEntries[] = {
{ "STRING", 0, 0 }
};

on the Tree View. In the Gtk 1.2 version of my app I had it set to 
"text/plain" but this now didn't work. I didn't have to set the Text 
View up at all because it was set by default.

And I used this on the Tree View:
gtk_drag_source_set(GTK_WIDGET(view), GDK_BUTTON1_MASK, targetEntries, 
TARGET_COUNT, GDK_ACTION_COPY);

Once I did that I could drag from the Tree View to text boxes in the 
same app or other apps.
