Getting Weirdness In Media Library

Preface: If I add a status via this plugin and it pulls in a thumbnail, it automatically adds it to the media library.

The problem is…if I click on the main media library link from the admin menu – limited info is there, but no image. (screen 1)

Now let’s say I want to edit the status using the posts area. If I click to ‘add media’, the thumbs *ARE* there (screen 2), but if I try to add one of them to a post nothing shows up.

I’m using WP 3.5 and the Dionysus theme.

Any idea what the heck is going on?
