Summary:

SELinux is preventing the gconf-defaults- from using potentially mislabeled
files (%gconf.xml).

Detailed Description:

SELinux has denied gconf-defaults- access to potentially mislabeled file(s)
(%gconf.xml). This means that SELinux will not allow gconf-defaults- to use
these files. It is common for users to edit files in their home directory or tmp
directories and then move (mv) them to system directories. The problem is that
the files end up with the wrong file context which confined applications are not
allowed to access.

Allowing Access:

If you want gconf-defaults- to access this files, you need to relabel them using
restorecon -v '%gconf.xml'. You might want to relabel the entire directory using
restorecon -R -v ''.
