well the console is launched but I cannot do anything with it...

dirty solution:
install gdm, keep lightdm as window manager.

console is launched and seems to be workable. will update after some tests.

I don't think this bug is a duplicate; #877318 is GTK/theme related, while this one is Python DBUS related.

I just upgraded 10.04LTS to 12.04 LTS, then installed nanny. It does not show errors in the console when launched (just warnings about gtkSpinButton and the XML related stuff also mentioned above), then quits. At the moment, I do not have time to dig into this very much, but if I re-raise the exception (in /usr/sbin/nanny-admin-console), I get the following dump on the console:
