Are you aware you created $key but set $keymaker?

Sadly this isn't a script which I can use to reproduce the problem
though - the code to set up $this and $keymaker is missing.
If $keymaker vs $key is a typo, then the issue might be the lifetime of
the XapianMultiValueKeyMaker object - you need to ensure this is valid
for as long as it might be used as currently the C++ reference to it
isn't tracked, e.g. by setting:
$this->keymaker = $key;
Otherwise I don't know, and right now I don't have time to try to
reproduce the situation. If you can't supply a self-contained script,
please open a ticket at: http://trac.xapian.org/
