I seem to remember that Jeremy Whiting found several service files that
contained wrong data and file paths, though I do not remember the details,
nor do I know whether the bad files would affect your situation.  I think the
same problem (with the files) may also exist in Macports' KDE 4 ports.

I think there is an option in kdeinit4 that makes kdeinit4 fork and re-exec
itself, ostensibly to avoid the problem you mention.
