missing dependency gir1.2-rsvg-2.0

[Thorsten2k3]

Starting failes with:

ERROR:root:Could not find any typelib for Rsvg
Traceback (most recent call last):
  File "/home/thorsten/bin/fogger", line 45, in <module>
    import fogger
  File "/opt/extras.ubuntu.com/fogger/fogger/__init__.py", line 26, in <module>
    from fogger import FoggerWindow
  File "/opt/extras.ubuntu.com/fogger/fogger/FoggerWindow.py", line 37, in <module>
    from fogger_lib.BackgroundLoader import get_chameleonic_pixbuf_from_svg
  File "/opt/extras.ubuntu.com/fogger/fogger_lib/BackgroundLoader.py", line 1, in <module>
    from gi.repository import Rsvg
ImportError: cannot import name Rsvg

After installation of gir1.2-rsvg-2.0 everything is fine.

I'm using Ubuntu 12.04.1 LTS with Awesome WM. My Installation is a bit uncommon therefore I guess normal users doesn't bug the error.
