"sugar-control-panel -l" gives non-fatal error

When running "sugar-control-panel -l", I get the following output:

[fran@grackle ~]$ sugar-control-panel -l
ERROR:root:Exception while loading extension:

I've attached a small patch that fixes this.

Import dbus.service in network.py

Bug confirmed, patch reviewed and tested. Tomeu, can you r+ this, please?

Fran, please remember to follow the  Code Review process. In particular, please use "git format-patch" to produce the patch so the commit message gets included, and set the keyword r? so that the module maintainers will notice the patch.
Thanks for your ongoing work on fixing bugs, it's much appreciated!

Affecting deployments, in particular teacher training, since it prevents clearing the registration with school server. Workaround being used is a brute-force rm(1) of .gconf. Fix tested on XO-1.5 with Sugar 0.84.
