coherence crashed with ImportError in <module>()

Binary package hint: coherence

Couldn't get the totem plugin activated. Tried doing this from the command line:

/usr/bin/coherence -o use_dbus:yes -o controlpoint:yes

and that's when I got this error

fahim@fahim-x64:~$ /usr/bin/coherence -o use_dbus:yes -o controlpoint:yes
Traceback (most recent call last):
