Media Gallery SWF Uploader fails with session error

Under certain conditions, the new Media Gallery Flash Uploader may fail with a session error.  To resolve the issue, update the following 3 files:

private/plugins/mediagallery/templates/swfupload.thtml

public_html/mediagallery/album_rpc.php

public_html/mediagallery/common.php

These updates should only be applied to glFusion v1.1.7.  These updates are included in pl1.
