[gedit-list] Gedit Snippets won't start

[Michael Hill <mdhillca fastmail fm>]

I had Snippets working a couple of weeks ago but have upgraded since
then (openSUSE GNOME Factory); now I get this...

Traceback (most recent call last):
  File "/usr/lib64/gedit/plugins/snippets/__init__.py", line 19, in
<module>
    from windowactivatable import WindowActivatable
  File "/usr/lib64/gedit/plugins/snippets/windowactivatable.py", line

    class Activate(Gedit.Message):
  File "/usr/lib64/gedit/plugins/snippets/windowactivatable.py", line

    iter = GObject.property(type=Gtk.TextIter)
  File

Suggestions?

Thanks,
