problems with *.desktop in KDE

[dune@home.pl]

Hi,

I have just finished kups (KDE front-end for CUPS) but
I still have a small problem with updating KDE menu.

The package installs 'kups.desktop' in /usr/share/applnk/System 
properly but how I can update KDE menu automatically (or automagically from debian/rules) to see this new entry after installation?

The most funny is that KDE menu editor shows a menuitem of kups 
exactly as I expect.

(Probably this is question to rkrusty@debian.org :-)

Thanks in advance for help
