All the API's on this library work perfectly with my setup, except for the _delete_multipart, which always fails with a signature exception:

libcloud.common.types.InvalidCredsError: SignatureDoesNotMatchThe request signature we calculated does not match the signature you provided. Check your key and signing method.

Have you ever seen this? Any idea?
