The order does not seem to matter.

If I remove all but Core, it does not start.  If I remove just Core,
things are OK.

Also, if I add another valid category to the list, things are OK.

Since my $prefix is different, I looked
in /opt/kde/v3.5.7/share/applications.  I found the following:

: riddler 55#; fgrep \;Core\; *
Help.desktop:Categories=Qt;KDE;Core;
Home.desktop:Categories=Qt;KDE;Core;
KControl.desktop:Categories=Qt;KDE;Core;
Kfind.desktop:Categories=Qt;KDE;Core;

: riddler 56#; fgrep \;Settings\; *
kappfinder.desktop:Categories=Qt;KDE;Settings;
kcmkicker.desktop:Categories=Qt;KDE;Settings;
kdepasswd.desktop:Categories=Qt;KDE;Settings;
kgamma.desktop:Categories=Qt;KDE;Settings;X-KDE-settings-peripherals;
kpersonalizer.desktop:Categories=Qt;KDE;Settings;
kwalletmanager.desktop:Categories=Qt;KDE;Settings;
printers.desktop:Categories=Qt;KDE;X-KDE-settings-hardware;Settings;

The only problem is I'm not sure where in the menu structure these files
live so that I can attempt to start them.
