Uploads silently failing/pausing with new carrierwave_direct gem when uploading to s3

Question

i am having a small problem uploading files to s3 with new carrierwave_direct gem

I have followed the instructions for installing and setting up carrierwave_direct, however when i try to upload to s3, the upload begins and then pauses the upload at some point. Any thoughts?

Also sometimes i get this message from s3:

<Error>
    <Code>InvalidPolicyDocument</Code>
    <Message>
        Invalid Policy: Invalid 'expiration' value: '2011-09-13T07:52:58+02:00'
    </Message>
    <RequestId>"some id"</RequestId>
    <HostId>
        "some host id"
    </HostId>
</Error>

I have created an initializes file called carrierwave.rb with all my credentials from amazon s3. I have also loaded all the required gems(carrierwave_direct, fog, carrierwave)

Checkout my code here on gist

Has anybody else been able to get this working

Thank for for the help
