resourceBase trailingslash URL incorrect on Windows

When CiviCRM v1.4 is installed on a Windows XP machine. The IMG SRC tags are incorrect. The problem stems from the $config->resourceBase variable has an extra '\' added by the addTrailingSlash in modules/civicrm/CRM/Core/Config.php

An example of the broken IMG SRC tag is below.

src="/modules/civicrm/\i/admin/Profile.png" alt="CiviCRM Profile"/>

The section of code with the problem in Config.php is..
if ( defined( 'CIVICRM_RESOURCEBASE' ) )

{ $this->resourceBase = self::addTrailingSlash( CIVICRM_RESOURCEBASE); }

I believe this needs to be changed to
if ( defined( 'CIVICRM_RESOURCEBASE' ) )

{ $this->resourceBase = self::addTrailingSlash( CIVICRM_RESOURCEBASE, '/' ); }
