I found a patch that resolves the "eject -T" problem:

https://bugs.launchpad.net/ubuntu/+source/eject/+bug/91873

The patch works.

There remains a permissions problem. As normal user, from the command line, kdeeject fails but sudo kdeeject succeeds. With the former the icons won't disappear and with the latter they do.
