APR::Request::Apache2 param() method

Hi,

I am having a strange problem with APR::Request::Apache2 and the param 
() method.  When I send a POST from Firefox, my code works  
perfectly.  When I send a POST from Safari or Windows/IE, my code fails.

Here is the HTML which displays the form to send:
         <form name="delete_alert" action="/mailing_list/remove"  
method="post" enctype="multipart/form-data">
         <input type="hidden" name="alerts_id" value="1234" />
         <input type="hidden" name="alerts_email"  
value="[email protected]">
         <input type="submit" name="submit" value="Remove">
         <input type="button" name="cancel" value="Cancel"  
onclick="document.location='/'; return false;">
         <br class="clearing">
         </form>

Here is the Perl code which handles this request:

     my $req = APR::Request::Apache2->handle($r);

     my($arg_status,$body_status) = $req->param_status();
     $r->log->debug("Parsing returned $arg_status, $body_status");

     if($r->method_number() == Apache2::Const::M_POST)
     {
         my $ps = $req->param();
         foreach my $k (keys(%$ps))
         {
             $r->log->warn("Got $k => " . $ps->{$k});
         }
         ## verify that we got an  alert id
         my $alert_id = $req->param('alerts_id');
         my $alert_email = $req->param('alerts_email');
         $r->log->debug("!!!!!!!!!!!! Checking params");
         if(!$alert_id)
         {
             $r->log->warn("no alert id given");
             return show_form($class, $r, $Site, $req, "Must pass a  
properly formatted alert id");
         }
         $r->log->debug("Have a good alert id");


Again, when Firefox sumbits this request, the code works perfectly...  
Here's a snippet from the error log showing the statements:

Any suggestions on how to fix this?  My platform is:
