Error and possible race condition in the assets/uuid/data endpoints.

It looks like we might have a race condition in the assets/uuid/data endpoints. perhaps the assets in general. I noticed my calls were successful about 5% of the time. I put in a 1s wait, and now it's over 95%. When it fails, I get this error:

{"error":"web_application","timestamp":1391230754494,"duration":0,"exception":"javax.ws.rs.WebApplicationException","error_description":"com.sun.jersey.api.MessageException: A message body reader for Java class com.sun.jersey.multipart.FormDataMultiPart, and Java type class com.sun.jersey.multipart.FormDataMultiPart, and MIME media type application/octet-stream was not found.\n"}
