Bug#795615: mate-tweak: Cannot start due to missing Notify python package

[Satish BD]

Package: mate-tweak
Version: 3.5.0-1
Severity: important

Dear Maintainer,

mate-tweak cannot be started due to some missing dependency:

    mate-tweak
    Traceback (most recent call last):
      File "/usr/bin/mate-tweak", line 32, in <module>
        from gi.repository import Gdk, GdkPixbuf, Gio, GObject, Gtk, Notify
    ImportError: cannot import name Notify

I checked that I do have python-gi installed:

apt-cache policy python-gi
python-gi:
  Installed: 3.16.2-1
  Candidate: 3.16.2-1
  Version table:
 *** 3.16.2-1 0

        -10 http://httpredir.debian.org/debian/ sid/main amd64 Packages
        100 /var/lib/dpkg/status


but it doesn't contain Notify.py
