Description of problem:
System->About Fedora causes yelp to complain:
"Could not load document
The Uniform Resource Identifier
âghelp:/usr/share/doc/fedora-release-5/about/C/about-fedora.xmlâ is invalid or
does not point to an actual file."

This menu item is supplied by /usr/share/applications/about-fedora.desktop in
the fedora-release package.  It contains this line:
Exec=yelp file:///usr/share/doc/fedora-release-5/about/C/about-fedora.xml

However, the package contains the "about fedora" documentation (and release
notes etc) below this subdirectory: 
/usr/share/doc/fedora-release-5.89/

So it lookt like the URL needs to be kept in sync with the actual location (or
perhaps use a symlink?  I haven't looked at the specfile)

Version-Release number of selected component (if applicable):
fedora-release-5.89-rawhide

How reproducible:
100%
