Did you use the target structure to define the targets? Remember
that GTK+/GDK reffers to target as type.

Also you can check the target type in the drag context.

gboolean target_supported = FALSE;
GList *next = dc->targets;
while(next != NULL)
{
 const gchar *atom_name = (const gchar *)gdk_atom_name(
  (GdkAtom)next->data
 );
 if(atom_name != NULL)
 {
  /* Check it, it's a string. */
  if(we_support_it(atom_name, "folder"))
   target_supported = TRUE;
 }
 next = next->next;
}
