Description:
------------
mysql_fetch_array and mysql_fetch_assoc return empty arrays when, for the same query, mysql_num_rows returns 5 - the correct number.
also notable, the mysql_affected_rows causes a server malfunction for the same query.

I have tested it both on my 
public webserver (unix, unknown webserver, PHP 4, MySQL 4) and my home computer (Windows XP, Apache2, PHP 5, MySQL 5), 
thus this problem would appear to not be related to just one circumstance.

The really weird thing is that phpMyAdmin can read the database perfectly.

Reproduce code:
---------------
<?php

		$con = mysql_connect("####" ,"####" ,"####");
		if (!$con) {
			trigger_error("Unable to connect to mysql, MYSQL ERROR: " . mysql_error(),E_USER_ERROR);
		}
		if (!mysql_select_db("NuevasIslas", $con)) {
			trigger_error("Unable to open database, MYSQL ERROR: " . mysql_error(),E_USER_ERROR);
		}

while($row = mysql_fetch_array(mysql_query("SELECT * FROM `jaydev_config`"))) { 
	$config[$row['name']] = $row['value']; 
}

print "$config";

//print mysql_fetch_array(mysql_query("SELECT * FROM `jaydev_config`"));

?>

Expected result:
----------------
Array
(
[enabled_login] => 0
[enabled_register] => 1
[server_name] => JayDev
[url_base] => http://ni.shadyindustries.biz/jaydev/
[url_forum] => http://forum.shadyindustries.biz/viewforum.php?f=4
)  


Actual result:
--------------
Array
