Hi!

I've just investigated this, and found out that this is something I can't fix in Xdebug. mysqli_free_result() destroys the internal object, but leaves the resource (in your case, $rs) in a silly state. All Xdebug does internally is basically a var_dump( $rs ), and after it is freed with mysqli_free_result(), that throws exactly the same error (without Xdebug). This can however, easily be fixed in the MySQLi extension with the following patch:

I've filed a bug for mysqli pointing at this bug report. It is at https://bugs.php.net/bug.php?id=63486
