maliit-framework import fails in python using GI API

Using Ubuntu Xenial 16.04 with xenial-updates applied.

Installed gir1.2-maliit-1.0 0.99.1+git20151118+62bd54b-0ubuntu3 and dependencies.

Expected: successful import of Maliit via GObject Introspection API using python "from gi.repository import Maliit",

Observed: failure to import, error is "ImportError: cannot import name Maliit",

Diagnosis: the package is missing a .typelib file normally installed in /usr/lib/girepository-1.0

Impact: low, log spam; sugar-session package uses it (/usr/share/sugar/extensions/deviceicon/frame.py), but does not list it in dependencies, and hides the exception.
