It seems that http://bugzilla.gnome.org/show_bug.cgi?id=122569 and the
above are one and the same. I can confirm that the patch
http://bugzilla.gnome.org/attachment.cgi?id=26172&action=view appears to
have fixed my problem as well.
I'm also attaching the diff I promised that allows one to specify
gtk.TYPE_NONE as the third element of __gsignals__ tuple. If there is
something I need to do to make it better, please let me know.
Thanks.
