You shouldn't be accessing _cPtr explicitly yourself - it's a SWIG
implementation detail, and might change in the future.

This doesn't work because subclassing Xapian classes in PHP isn't
currently supported, so your $Decider object isn't a XapianMatchDecider
as far as SWIG is concerned.

SWIG now supports it, but I've not yet managed to get this to work with
Xapian.  This is the ticket:

http://trac.xapian.org/ticket/488

Sorry, there isn't really a workaround, other than avoid needing to
subclass MatchDecider, etc, or use a different language instead of PHP.

As far as I'm aware, this isn't fixed yet.
