Can you try using kdeeject from the command line on
your CD
drive to see if it works at all?
I tried, The result was an OK button dialog, "Eject failed!" I had everything in
kdebugdialog enabled and I could not find anything related.
That "Eject failed!" dialog should provide some verbose information about the
failure, or provide a "More details" button to provide why the command failed.
