My apologies.

I'm curious myself. Perhaps I misremember and the reason was a mistake
I made. If so, then I wonder if it was a mistake I made, because I was a
fool or because there is something that easily could happen, even if a
user is careful. Or do I remember correctly that there is a(n
exceptional) case that causes the find command to fail?

Unfortunately I couldn't find the thread by an Internet search and I
don't have access to my old emails at the moment, to search email
bodies.

Seemingly a lot of users used find for this purpose without trouble, so
perhaps I just was a fool.

I have to admit that I sometimes typ very fast and push enter, e.g.
"rm /a/path/ *", but it should be "rm /a/path/*" without a space ;).
Nowadays I'm in the habit typing "rm -I" and "mv -i" and sometimes to
mount partitions read only, so I not that often need to restore
from a backup ;).
