It's supposed to get unreferenced by gtk_text_btree_remove_tag_info(),
called from _gtk_text_btree_notify_will_remove_tag(), which is called
for gtk_text_tag_table_remove() but not gtk_text_tag_table_finalize().
So the tag table finalizer needs to handle this case.

Be sure it's in bugzilla, I'll need to do a pass through TextView bugs
for 2.0.1.
