[autoblog issues] sql warning

Hi !

2 things about autoblog :

1 - get this Warning: mysql_real_escape_string() expects parameter 1 to be string, object given in /home/creart/public_html/wp-includes/wp-db.php on line 785 when processing on the receipient blog

2 - Each new article created by autoblog creates a "comment" on the orginal blog on the original post. Is it normal ?
