Updating with Paperclip

I cannot seem to get paperclip working for my file uploads after switching from attachment_fu. I have the correct fields migrated into the database, have included has_attached_file :photo, :styles => { :thumb => "175x175>" } in my mode, but no photo is ever saved in the database and there are no errors. Looking in the console I noticed that it says paperclip is "Saving files for photo" and then on the next line "Deleting files for photo". Im wondering if this is a clue to my problem? The surrounding output is below:

Processing SpecController#update (for 127.0.0.1 at 2009-02-05 23:05:11) [PUT]   Session ID: BAh7CDoJdXNlcmkHOgxjc3JmX2lkIiVlNDdkZjcwNWY0YzViODRlOTZjNGJi M2FiMTU4YzMxOCIKZmxhc2hJQzonQWN0aW9uQ29udHJvbGxlcjo6Rmxhc2g6 OkZsYXNoSGFzaHsABjoKQHVzZWR7AA==-- be12b27be21dd16e1c3fe915b78e06d0173a08c2   Parameters: {"commit"=>"Upload", "authenticity_token"=>"0116a623cd3b784f7c81539c52b6e0c04cf0c611", "_method"=>"put", "action"=>"update", "spec"=>{"photo"=>"Blue-Wild- Flower-1-1024x768.jpg"}, "id"=>"10", "controller"=>"spec"}   User Columns (0.006779) SHOW FIELDS FROM `users`   User Load (0.028061) SELECT * FROM `users` WHERE (`users`.`id` = 2)   CACHE (0.000000) SELECT * FROM `users` WHERE (`users`.`id` = 2)   Spec Load (0.000263) SELECT * FROM `specs` WHERE (`specs`.user_id = 2) LIMIT 1   Spec Columns (0.002173) SHOW FIELDS FROM `specs` [paperclip] Paperclip attachment photo on Spec initialized.   SQL (0.001320) BEGIN [paperclip] Saving attachments.

This is my controller action(for testing):

def update     @spec = logged_in_user.spec || logged_in_user.spec.build(params [:spec])     @spec.update_attributes(params[:spec])   end

Anyone have any ideas, this is driving me crazy.
