Comment (by nullreturned):

 I haven't done too much debugging, but I'm getting the same issue as well.
 Anything I try to upload to the Media that's over 1MB in size is giving
 the same exact error.  I've tried this with multiple file types.  Anything
 over 1MB takes a very long time, and then errors with: "Unexpected
 response from the server. The file may have been uploaded successfully.
 Check in the Media Library or reload the page." and nothing actually
 uploads.  It is also insanely slow to get this to process through, and I
 have fairly fast (150mbs) uploads.

 Files smaller than 1MB have no issues and are processed immediately.  I've
 checked my host's phprc file and don't see anything that would limit it.
 I had turned on debugging, and no errors were returned (strangely).  I've
 verified that both WordPress and my Host is set to limit it at 64M, so I'm
 not sure where the culprit may be.
