For instance, when using the S3 Boto backend, my admin renders the following line: {{{ }}} Which, when concatenated with the fixed string generates the invalid URL: https://oca3\u002Dqa.s3.amazonaws.com/admin?Signature\u003DXIt%2FCc9wPWjaw%2F3ITNjkYE3bc%2FI%3D\u0026Expires\u003D1356844210\u0026AWSAccessKeyId\u003DAKIAIGREZ7J53KZ23QKQimg/icon_clock.gif I suspect that the assumption the DateTime widget is relying on ({% static a+b %} should be equivelant to {% static a %}b) is invalid, and it should be using a more robust method to determine the static URL of its resources. The DateTime widget appears to be the only element depending on !__admin_media_prefix!__, and thus the only one to fail when switching to a backend that doesn't support its assumption."
