Problems with "update" operations

Hi,

   Recently I started to have problems with updating annotations in 
Annozilla. After a bit of investigation I am starting to think it might 
be a server problem, and was wondering if anyone was seeing the same issues.

   I had been testing with the annotest server, but after I started to 
run into problems - getting 500 errors when trying to delete my 
annotations - I installed a server locally, using CVS tag V1_2.

   What I seem to find, using 
http://www.w3.org/2001/Annotea/User/Protocol.html as an example, is:

1. If I use the "PUT" method of updating, then it seems to work, but I 
don't get any annotations for the page when I reload.

2. If I use the "POST" method of updating, then I get back 201 for the 
annotation, and the update seems to work. But if I "DELETE" the 
annotation, then I get back a 500 error, because two annotations with 
the same id exist. (This looks like the same kind of problem I was 
having with annotest.)

Amaya seems to have some similar problems - if I update an annotation, 
then I get an error message back when I try to reload it.

Any thoughts? Does this sound like a server installation error or a 
software problem?

I found the problem, for this case at least. It's an incompatibility 
with the version of CGI.pm. Later versions of CGI.pm require something 
like this:
