Bug#813743: pitivi: Fresh install of Pitivi failing to start with missing dependencies

[Richard Decal]

Package: pitivi
Version: 0.93-4.2
Severity: important

Dear Maintainer,

I just installed pitivi on Debian running LXDE. When I try to start it I get
this error:

 ~ pitivi
Failed to initialize modules:  No module named gi.repository
ERROR - The following hard dependencies are unmet:
==================================================
- Clutter not found on the system
- ClutterGst not found on the system
- Gst not found on the system
- GES not found on the system
- Gtk not found on the system
- Gio not found on the system

    from gi.repository import Gst
ImportError: No module named gi.repository


As per this closed bug (https://bugs.debian.org/cgi-
bin/bugreport.cgi?bug=743692) I tried apt-get installing gir1.2-clutter-gst-2.0
but that did not fix my problem.
