Filefield alias not the same as Views field when rendering data

In views/filefield_handler_field_data.inc the render function uses filefield field_alias to try to obtain a value from the view result. This isn't necessarily going to be the same as the views field alias as Views likes to change field aliases around a bit.

I'm not sure if this is a problem with filefield or views but currently I can't display the contents of a data field.

I'm using a clean install of Views 6.x-3.0.
