Comment 16 for bug 781737

I imagine the difference between versions of Ubuntu and therefore Policykit are causing this, as it will not build either. Can the patch please be updated for Ubuntu 12.04 x86? Without it I am still stuck with the behaviour I originally reported in bug https://bugs.launchpad.net/ubuntu/+source/policykit-1/+bug/892680
