Fw: gnats(web) occasionally submits duplicate PRs

Oh,... I do see something similar now in the gnats bugs database at 
http://gnats.wookimus.net/cgi-bin/gnatsweb.pl?database=gnats in #507. One 
of my users did say that he submitted another PR by using the Create menu 
bar while the confirmation page was still open, and then the first PR was 
submitted again later, which seems to be the situation described in #507. 
I am able to re-create the problem using the steps in that PR, I think. If 
so, that would point to a gnatsweb problem. I'm not totally convinced, 
though, because of the case where a duplicate was submitted less than a 
second later, with no PR being submitted in-between. I am not able to 
re-create that problem. But I'll look at the gnatsweb code and see if I 
can find a problem with the return_url.
