You can safely delete the 11 mentioned lines in the
......tdemenuedit.menu -file, you'll find the same entries there again,
though starting with tde-....., nothing is lost.
Then delete the ....test9.txt file in /var/tmp/tdecache-$USER, end the
current session and restart it again. Now only one error-warning pops
up and if you again restart the session, also this pop-up has
disappeared.
Yes, I uttered quite some strong words when I encountered that nuisance
and had to put the puzzle together:-)

Kind regards, Peter.
