Some Gnome menu items unresponsive on FC6 test 1 as user

[Stanton Finley]

I am not able for example to change the panel browser icon from default
to firefox.png by right clicking the default icon, selecting
"Properties", clicking "Icon:" and trying to select the firefox icon.
"System" > "Administration" apps do not appear at all or if they do
appear are not responsive. For example "Login screen" does not allow a
selection and requires a force quit to close.
