Fail to open all system setting from gnome panel

[Wong Kwok-hon]

Hi!

After I run FC3 for two day, I discover all fine excepted fail to run
system setting gui(s) (e.g. user/group setting, bootloader setting
program) with no response.

In FC2, all works group and I just put the FC3 disc1 when boot. It
upgrade it ok but fail to run these setting programs....

Any help please.
