[Plugin: qTranslate slug with widget] MySQL error when updating to 0.6

Hello,

After updating your plug-in I get the following error:

Warning: mysql_real_escape_string() expects parameter 1 to be string, object given in /home/ins10001/public_html/cookgoods/wp-includes/wp-db.php on line 789

Can you please look into it?
