Media module support broken for media-2.x branch

I don't know, actually, but I've cross posted this in the File Entity issue queue at #1309168: media_edit form changes breaks image javascript crop to see if there are any answers forthcoming. For the record, the situation is unchanged with today's latest:

imagecrop-7.x-1.x-dev (2011-Oct-05)
media-7.x-2.x-dev (2011-Oct-13)
file_entity-7.x-2.0-unstable2

And here's a screenshot of what I'm seeing (note the lack of thumbnail or 'edit image' button for the crop)...

@zuuperman: As it stands, Imagecrop works correctly with the Media-7.x-1.x branch - but according to that project's maintainers, the Media-7.x-2.x branch is the way forward, and part of the change was to abstract out some of the file handling bits to a new module: file_entity.

Possible solution: As of imagecrop-7.x-1.x-dev (2011-Oct-13), I was able to get Imagecrop to work simply by duplicating function imagecrop_form_media_edit_alter (lines 169-196 in imagecrop.module) and renaming the copy to imagecrop_form_file_entity_edit_alter.

Leaving the original hook_form_FORM_ID_alter implementation keeps things working for media-7.x-1.x, while the new version correctly hooks into the new media/file_entity way of doing things. I tested it with a fresh upload and an existing upload and it seems to work: I get the 'crop this image' button, which fires the popup and allows to me correctly set all the imagecrop-enabled image presets.

The preview thumbnail still isn't appearing, but I'm not sure if that's imagecrop's problem or file_entity/media's...
