In my book that is progress. First make sure that the directory
/usr/share/gdm/themes/Default exists. If not then what some else
mentioned yum upgrade gdm is your answer.
If it does then you need to work out why permissions or such are being denied.

The file is very well commented. You can find a line saying something
about greeter? change this to standard instead of graphic. See the
line which pertains to remote greeter.
