I took another look at polkit's and gnome-shell's source code. I didn't do it before since I have work to do and (as I said) the problems are somewhat workaroundables. After looking at the code, the plot thickens: gnome-shell registers itself to polkit as a PolkitUnixSession: http://git.gnome.org/browse/gnome-shell/tree/src/shell-polkit-authentication-agent.c?id=3.4.2#n106 polkit will not deal with that in subject_to_jsval: http://cgit.freedesktop.org/polkit/tree/src/polkitbackend/polkitbackendjsauthority.c?id=0.107#n730 The funny thing? Both code paths were written by David Zeuthen, which by the way is the one handling the bug. It gets better: I changed gnome-shell's code so it registers itself as PolkitUnixProcess (which supposedly is handled by subject_to_jsval), and I put printf's in the function subject_to_jsval. It turns out that, no matter that it actually gets registered as unix-process, gnome-shell it's also registered (at some point) as unix-session. My feeling is that gnome-shell should get registered as system-bus-name (which it does), and that should be the "primary" interface of gnome-shell for polkit. However, in Gentoo (I haven't found any other mention of this bug in any other distro), somehow the unix-session interface takes control. I updated the bug: https://bugs.freedesktop.org/show_bug.cgi?id=53905 and I hope David will respond soon.
