Per discussion: https://www.redhat.com/archives/fedora-devel-list/2007-September/msg01381.html Please update .desktop files to include the name of the app in the Name= field, ie, fedora-xsane.desktop to contain (something like): Name=xsane GenericName=Scanner Tool or Name=xsane Scanner Tool (and not use GenericName at all)
Deferring until GNOME has the necessary infrastructure to cope with the Name, GenericName entries as specified by the desktop spec.
