When Uploading files, all sorts of crazy errors.

I have tried both the beta-4 and the dev versions, I have a field collection with an image and a video field. Trying to upload a file to either causes a lot of issues. Unfortunately I'm not going to be able to use this for this project because it seems a bit unstable yet. But I thought maybe I could help out because the concept of the module is fantastic and I really hope to see it mature. Let me know if I can provide any additional information that will help.
