RC2 LXDE spin two polkit invocations

Mon Aug 9 11:22:42 UTC 2010

Installed lxde-x86_64-20100806.15.iso, and everything seems to work.
However, upon starting X (from runlevel 3) I get the following error:

Remote Exception invoking
org.freedesktop.PolicyKit1.Authority.RegisterAuthenticationAgent
() on /org/freedesktop/PolicyKit1/Authority at name
org.freedesktop.PolicyKit1:
org.freedesktop.PolicyKit1.Error.Failed: An authentication agent
already exists for session Cannot register authentication agent

Looking in /etc/xdg/autostart, I see two invocations of polkit:
  lxpolkit.desktop
  polkit-gnome-authentication-agent-1.desktop
which come from
  lxpolkit-0.1.0-0.1.20100402git5087383.fc14.x86_64
  polkit-gnome-0.96-2.fc14.x86_64
respectively. Eliminating the latter seems to be the fix
