[Plugin Polyglot] Sudden error

Hello all,

I use Polyglot since almost the beginning of my blog. And suddenly, with the version 2.5 on WP 2.9 I get an warning (low level error), though it only appeared very recently, NOT when I installed 2.9.

Warning: Parameter 1 to polyglot_filter_array() expected to be a reference, value given in wp-includes/plugin.php on line 167

Thanks for all help…
