Indeed, but still, if there is a use for KDE System Settings to appear
on the Gnome desktop, then Shaun solution is appropriate IMO, but that
actually brings another interesting question:

Which KCM (KDE Control Module, the elements shown in KDE System
Settings) are actually useful when running on Gnome?

As I said, to the best of my knowledge, very few applications must be
configured from a KCM. The only two applications I found on Ubuntu are
KInfoCenter and KNemo, which are both KDE workspace-specific. A regular
(meaning with a main window) application should show its configuration
through its "Settings" menu. A window-less application is most likely
workspace-specific and would probably not be useful on a different
workspace. Do we have examples of KDE window-less applications which are
useful on Gnome?

Another use for KDE System Settings on Gnome is the configuration of the
palette, font and icon settings of KDE applications. Interestingly I
pushed yesterday a commit which makes KDE applications follow the
workspace settings for palette and font (I have yet to do icons) when
not running on a KDE workspace, just like Qt-only applications do (BTW,
would be awesome if you Gnome devs could do the same for Gnome
applications running on a KDE workspace). So this is not relevant anymore.

If there is no need for KDE System Settings on a Gnome desktop, then
adding a OnlyShowIn=KDE; key to the desktop file would be appropriate.
If on the other hand there is a need for KDE System Settings on a Gnome
desktop, then Shaun solution is correct IMO and we should start to think
about adding support for OnlyShowIn to KCM desktop files, because it
makes no sense for example to be able to define Plasma Desktop wallpaper
when running on Gnome.
