Version 0.4.1 breaks chai test for `fileupload` data attribute

[mitnal]

I am not really sure if it is a problem of jquery-fileupload-rails but I have no other clue than that 0.4.1 fails my test and 0.4.0 passes. Perhaps somebody has a similar problem or can help me with this error.

describe 'Fileupload', ->

  it 'initializes the fileuploader', ->
      $('#fileupload').fileupload()
      expect($('#fileupload')).to.have.data('fileupload')

This passes with 0.4.0 but fails with 0.4.1 with the following backtrace:

TypeError: Cannot read property 'ownerDocument' of null
