I managed to fix this by changing my handler to a fixup handler and not setting 
any request handler at all. The fixup handler returns OK for HTML requests (it 
uses content negotiation and a GET param to decide what to return) and installs 
a relevant handler for other formats:

    return OK if $format eq 'html';
    $r->handler('modperl');
    if ($format eq 'json') {
        $r->set_handlers(PerlResponseHandler => \&handle_json);
    } elsif ($format eq 'xml') {
        $r->set_handlers(PerlResponseHandler => \&handle_xml);
    } elsif ($format eq 'text') {
        $r->set_handlers(PerlResponseHandler => \&handle_text);
    }

And now it works just how I want.

Thanks,

David
