The error you get here is actually a bug in SWIG (http://www.swig.org/).  Xapian
uses SWIG to generate the wrappers for Ruby.

The code SWIG currently uses to convert a parameter when a C/C++ function
takes a double doesn't handle a "fixnum" which is larger than MAXINT.  I've
just applied a fix to SWIG SVN:

http://swig.svn.sourceforge.net/viewvc/swig?view=rev&revision=11320

I'll make sure this fix makes it into the next Xapian release (which will be
1.0.14).

Cheers,
