You can check [1] to get some info about libpam-systemd doing
something wrong here.

Also we had this issue for months in Linux Mint before Clement Lefebvre
made a patch [2] that fixed it. After the patched libpam-systemd had been
released for Mint, the problem was gone. That was it. No patching gksu,
no patching dconf.

Well, that seems to work for me (I'm using MATE though - but it's affected by
the issue as well). But it's not a complete solution. Some apps are meant to
be run via gksu and have gksu without '-l' in their .desktop files. For example,
some of the reporters simply launched a root terminal and then ran some apps
in it. The .desktop file for launching that root terminal is shipped with gksu
itself and has no '-l' in it. Even if you tell users to remember to always run apps
manually with gksu (instead of using root terminal) and always specify '-l', they
might easily forget about that.

I heard several times it's not a good idea to use gksu, but no one suggested
a good, complete replacement for it. The current situation is that we have to use
it sometimes. A few apps like Synaptic or GParted have pkexec support, others
don't have it and we use gksu with them.

Ok, so maybe it's time to remove 'moreinfo' and 'unreproducible' tags?
