Ok. Appearantly the modification date of the desktop file is older than that 
of the sycoca file so it will not "see" the desktop file.

There seem to be four possible error scenarios:
1) kbuildsycoca crashes the first time it is run.
2) KDEDIR is set incorrectly so that kbuildsycoca uses the wrong
directories to build the database from.
3) KDEHOME is set incorrectly so that kbuildsycoca stores the database in 
the wrong place.
4) The modification dates of the desktop files are older ksycoca so that they 
aren't recognzed as "new".
