Well, I am now running a 2.6.22 (without cfs) and could now see it once
(within a month...) that exactly the same message from konqueror was
produced.
So I think its a general problem of konqueror that was hidden and
somehow its triggered much more often with the cfs.

Well, I am back now, but the problem still exists in 2.6.23-rc2.
And as there is nothing more I can do thats it for now.
