Comment (by jtclarke):

 Correction -- it affects post thumbnails and images as well.

 So -- steps to reproduce:

 Using a multisite installation of Wordpress 3.0.4, the TwentyTen theme and
 no plugins enabled (to eliminate any extraneous variables):

 1. Drop in Ryan et al's memcached client (object-cache.php)
 2. Drop in Batcache (advanced-cache.php)
 3. define( "WP_CACHE", true); in wp-config.php and enable memcached.
 4. Begin creating new posts in wp-admin.  With each new post, upload an
 image via the media uploader and try inserting as many sizes as are
 available into the post / Featured Image.

 For me, even on the first post, what I see is that only some of the image
 sizes are served correctly.  For example. I see the Full size and Post
 Thumb, but not the 150x150.  See screenshot1.png.  This affects the thumb
 in both wp-admin and on the frontend.

 If I try loading the failing image directly from its url (eg.
 http://flavordev.local.mu/files/2011/02/6413719-150x150.jpg), the image
 does not load -- all I get is the url string.

 When I disable WP_CACHE and remove object-cache.php and advanced-
 cache.php, all images appear as they should.  See screenshot2.png.

 If I restore object-cache.php and advanced-cache.php and re-enable
 WP_CACHE (making sure to clear my browser cache) the 150x150 disappears
 again.  See screenshot3.png.

 If I leave Batcache enabled and institute the change I suggested in the
 diff file, everything serves as it should.  See screenshot4.png.

 Let me know if you need any more information.
