Devise is not working with flash runtime of Plupload - ruby-on-rails-3

Question

I'm running Rails 3.0.9, Devise 1.4 and Plupload 1.4.3.2. Everything works fine with HTML5 runtime.
But when I add before_filter authenticate_user! to my application controller and switch to flash runtime things go bad.
When I try to upload some images:

Problem solved with adding
urlstream_upload: true
to the plupload configuration.
