Yes, I did that.  Two requests were really sent.  Sorry for forgetting
to mention it.  The odd thing is that the second requests were sent
just before the "Add Item" request, which seems incomprehensible to me.

This is why I was not inclined to change Koha to fix it, until/unless
it becomes obvious that Koha is triggering the duplication somehow.
But yes, I guess a once-only ID would solve this.  Do we have something
suitable in any of the perl modules we already use?  I didn't find one
on a quick look in CGI::Session.

I'd still like to hear of other instances of this problem...
