I think 406 is the status code used by mod_security when rejecting
pages.  That would imply to me that the page/POST content contains 
something that mod_security doesn't like, causing it to return a 406
HTTP status.  

So, I think something in the webserver configuration is translating that
to be a request for a custom 406.shtml page, then passing _that_ off
to PmWiki (which then complains about it being an invalid pagename).

Try posting the contents of the page to a different (temporary) page
(which should also fail in the same way).  Then you can start removing
content until you find out what mod_security is carping about.
