Just take a look at /etc/skel/.kde/share/config/kickerr and look ServiceButton sections. Make sure you have absolute path to the program and not relative path. Relative paths starts with $HOME and it is removed during remastering.

Here you see the difference:
Absolute path:

[ServiceButton_7]
DesktopFile=/usr/share/applications/mozilla-firefox.desktop
FreeSpace=0
StorageId=mozilla-firefox.desktop

Relative path:
DesktopFile=$HOME/.kde/share/apps/kicker/mozilla-firefox.desktop
