Description of problem: Making the script executable would make it possible to have XFce as the default desktop environment by just adjusting /etc/sysconfig/desktop, while right now you also have to hack /etc/X11/xinit/Xclients and remove the which invocation (or make the file executable yourself). Version-Release number of selected component (if applicable): xfce-utils-4.0.6-1
it's now fixed in xfce-utils-4.0.6-3. Thanks for your report.
