S3 image attachment works, but reprocess looks locally

[coneybeare]

Even though I have s3 specified and uploads/fetches working,
reprocess! want to look locally for the file instead.

>> a.image.url
=> "http://cloudfront.<REDACTED>.com/data/images/1/original.png?
1334279391"
>> a.image.reprocess!
Errno::ENOENT: No such file or directory - /data/images/1/original.png

The image is setup like this:

has_attached_file :image,
:styles => { :mini => "24x24#", :thumb =>
"64x64#" },
:convert_options => { :mini => "-auto-
orient", :thumb => "-auto-orient" },
:storage => :s3,
:s3_credentials => "#{Rails.root.to_s}/config/
s3.yml",
:url => ':s3_alias_url',
:s3_host_alias => "cloudfront.<REDACTED>.com",
:path => "/data/images/:id/:style.:extension",
:bucket => '<REDACTED>',
:whiny => false

Other than reprocess!, the uploads and url methods of paperclip work
as expected. What am I doing wrong?
