incorrect media:content/media:thumbnail url?

When "File path" in an image field is not set, media rss works. If a file path is added to an imagefield (see filepath.png), the image is created there as expected, and imagecache creates images and thumbnails in a subdirectory by that name under the corresponding preset. Problem/question is that media rss doesn't seem to find images if subdirectory set--whatever I'm using to display media rss views works if no subdirectory, doesn't work if a subdirectory is set.

The description from preview has the right path (subdirectory called "gallery"...)

http://www.gurnetroad.com/test/sites/www.gurnetroad.com.test/files/image...

but media:content and media:thumbnail are missing the additional subdirectory

<media:content url="http://www.gurnetroad.com/test/sites/www.gurnetroad.com.test/files/imagecache/BigPicture/062808_0033.jpg" type="image/jpeg" />
<media:thumbnail url="http://www.gurnetroad.com/test/sites/www.gurnetroad.com.test/files/imagecache/BigPicture/062808_0033.jpg" />

I'm confused because this http://www.gurnetroad.com/test/feeds/faces/rss.xml seems to reference the right location.

Not sure if this is something in my setup or if I'm doing something wrong....

Thanks.
