Error on heroku when denied privilidges on Facebook

I got a strange error in application. It happens when I try to sign in with facebook, and than on facebook deny app the privileges that it asks for.

Here's stack trace:

Started GET "/users/auth/facebook/callback?error=access_denied&error_code=200&error_description=Permissions+error&error_reason=user_denied&state=426366bb3ac72ca4ad2b8b3fea5d5c7f628d6463b5df64a6" for 95.51.182.141 at 2013-09-05 20:55:24 +0000
(facebook) Callback phase initiated.

Completed 500 Internal Server Error in 2ms

NoMethodError (undefined method `to_sym' for nil:NilClass):

   vendor/bundle/ruby/1.9.1/gems/mobile-fu-1.1.1/lib/mobile-fu.rb:89:in `set_request_format'
(...)

What's funny is that when I looked into mobile-fu code I saw that what's nil (and apparently shouldn't be) is params[:action].

I digged bit deeper and it seams that devise works funny that way, that sometimes params[:action] isn't set. Anyways it's an issue on divise <-> mobile-fu line, or that's what it seams.

Here's an issue on github (which is now closed):

The fix isn't what I would wish for, but perhaps there is a reason why params[:action] (and params[:controller]) isn't set
