I can do a non-maintainer upload of gobject-introspection, rebuilt for python3, 
to see if that helps.  I'm in the process of testing the build on Scallywag at 
the moment.  I'm using python37 because of the mako requirement.

I'd prefer to upgrade gobject-introspection to a more recent release rather than 
just rebuilding the current release.  But, unfortunately, a more recent 
gobject-introspection would require a more recent glib2.0.  I'm not sure it's a 
good idea to update glib2.0 without updating all of GNOME.  I tried to start a 
discussion about this last May, but it didn't get very far:
