Bug #51002 for POE-Component-Server-XMLRPC: XML parser throws exception on malformed request

Whilst playing with setting up an XMLRPC server and debugging firewall issues, I discovered that sending a malformed request (such as 'wget http://localhost:port/?session=service') would bring down the whole script with an uncaught exception from the internal XMLRPC::Deserializer call (since there is no valid XML payload to be decoded). Granted, this is an error condition, but it should probably reply with a 403 or 500 and keep running, rather than falling over completely. Attached is a short patch which fixes it for me by only parsing the payload after the content-type has been verified, and wrapping the call in an eval block which returns an error and continues serving. Thanks, Tom Feist.
