I'm not sure; I haven't heard of that tag before.  It may be the
mechanism that appearance control panels use to turn themes on and off.
Ideally the applet should be using it's own theme directory or something

The "auto eth0" connection is added because the platform has an ethernet
device, but there are no connections available to handle it.  In the
spirit of "Just Works", the system settings service creates an automatic
DHCP connection for that device so that when you plug it in, you get a
connection.  That automatic connection will go away when a real system
connection for ethernet devices is created.

That seems wrong; dbus activation is a bit hard to debug, mainly because
the helpers that actually spawn the activated services don't have
anywhere to dump logging information.  A few standard checks though...
what does the following command say when you run it *before* the
supplicant is manually started?

sudo dbus-send --print-reply --system --dest=fi.epitest.hostap.WPASupplicant /fi/epitest/hostap/WPASupplicant fi.epitest.hostap.WPASupplicant.getInterface string:eth2

(of course, replace "eth2" with your wifi device)

We need to debug the DBus system activation mechanism a bit.  It's
somewhat unforgiving about permissions, because wrong permissions can be
a security issue.

How about "pkg-config --modversion polkit-gnome" ?

You may need to install the PolicyKit-gnome-dev package, which should
have the right bits in it.  The "polkit-helpers/" directory is actually
just backported stuff from polkit-gnome to work with PolicyKit 0.6, but
PolicyKit 0.7 and later have polkit-gnome already.
