Description of problem: Fedora 19 Xfce. This Application Menu items do not work: "Administration / Users and Groups" "Administration / System-Config-Date" They would not start anything not to mention the bad name for the second one. The appropriate system-config-data and system-config-users are installed and work fine from the prompt.
This is sadly a known issue... we just haven't gotten a fix for it yet. *** This bug has been marked as a duplicate of bug 879922 ***
