Known bug: http://bugzilla.gnome.org/show_bug.cgi?id=127780.  I think
this has to do with the following commit:

Thu Sep 25 11:23:24 2003  George Lebl <jirka at 5z.com>
                                                                                
        * daemon/errorgui.c, daemon/slave.c: be even analer (is that
          a word?) about the setuid stuff here (it can't actually
          fail, but just in case, we're being paranoid)  Also reset
          the environment and desetuid for the setup program even
          though that's not really needed.

I'd add your info to the bug as it's definitely lacking some details.
