[JDEV] Bug report.. UPDATE!!

	Yes another update..  I'll now hand this over to you guys..  The error is
becouse of a call to XML_ParserFree(xp->parser); in free_xptpool.

	Actually, I can now tellyou exactly what it is (As I was writing the above
it hit me like a brick..)

	xpt_packet_new, which creates the parser for a connection, isn't called
untill the dispatch loop in handle.c.  And it isn't called untill there is a
call to dispatch with an IO_NORMAL flag.  When a disconnection comes before
ANY data is sent over the line, there IS no call to xpt_packet_new, and
hence causes XML_ParserFree to belch as it attempts to free something that
isn't there..

	I'd love to trouble shoot it further, but I glanced at XMLParserFree, and
I'm not that familiar with the inner workings of xmlparse.c.  Could we
simply have xpt_packet_new as soon as a connection is made, instead of
checking for it every time dispatch is called?
