Assuming this is a GNATS and not a Perl problem, try the following.
Go to the 'Edit Problem Report' page. Your browser will display a URL
something like:

http://<whatever>/gnatsweb.pl?cmd=edit&...

Edit the URL and insert a 'debug=all' as follows:

http://<whatever>/gnatsweb.pl?debug=all&cmd=edit&...

Then access gnatsweb with this URL. You will see a lot of communication
going on between gnatsweb and the gnats server (gnatsd). At the bottom of
the page you should be able to find the 'Edit' page again. Now perform the
edit and submit in the usual way. Again you will see gnatsweb talking to
gnatsd and hopefully this will reveal the reason for the hanging request.
