It does not have to be in the existing KCMs ;) (i.e. see what Ben wrote).
All I am saying is, not having a settings UI appear in SystemSettings but in 
the menu is rather confusing from a user POV.

Oh my bad, I was thinking of start-here.png, which is not suitable. Basically 
I think there are 2 options here:
a) ship your own icon
b) use oxygen.png

Latter is not very advisable iff you choose to have the app listed in the menu, 
as the implementation of the menu (think gnome-menu) is responsible for icon 
lookup, which of course then fails if the used icon set is not oxygen. For a 
KCM/SystemSettings entry that would be a none-issue as IIRC KIconLoader always 
tries to look for icons in oxygen as second to last option.

So, if your desktop file is only used within a KApplication (such as 
SystemSettings) you can use any icon from the oxygen set knowing that it will 
always be displayed, if your desktop file can be used by non-KApps you will 
need to ship an icon for the application and install it to the hicolor theme.

Also see [1].

[3] contains a list of all registred cateogires.
[2] is the main spec on desktop files, it points to other relevant specs as 
needed (which includes [1] and [3] of course ;)).

I do still believe that integrating the app to show up within systemsettings 
rather than the menu would be the way to go though :)
