I think I'm getting closer to the problem. The reason why I could not
reproduce the issue, was that I've been using libglib2.0-0 from
experimental (i.e. 2.30.1). If I downgrade to 2.28, I can verify this
bug, so I've marked it as serious, as pk-gnome should not enter testing.

I suspect the problem is due to this commit:
http://git.gnome.org/browse/PolicyKit-gnome/commit/?id=1d019a66f9eaf6cd472eecfa38ce462a1b12906c

Cheers,
Michael
