Ruby on Rails

After migrating my 2.3.9 app to rails 3.0.0 I get this error:

Completed 406 Not Acceptable in 513ms

I also noted that processing controller doesn't output the protocol:

-- Processing by Admin::PhotographersController#update as

while if it works, say:

-- Processing by Admin::PhotographersController#update as HTML

Here is the full action output http://pastie.org/1187051

Can anyone help me, please ?
Don't know where to start :-(
