[imp] Error when deleting mail

[EB]

using head

I get the following error when deleting mail.  However, I only get this if 'move
them to your trash folder instead of marking them as deleted?' is unchecked.

The mail is deleted even though I get the error.

Warning: mysql_real_escape_string() expects parameter 1 to be string, object
given in /usr/share/pear/DB/mysql.php on line 666


Please let me know what to try to correct this.

Thanks!
