Try to open one of the ram files on http://www.amazon.fr/gp/product/B000005TQO/ref=ox_ya_oh_product (links Écouter) in Firefox, and choose to open them in Totem (2.27.1). Totem gives the error:
Internal GStreamer error: pad problem

Other ram files on the Amazon.fr sites are working fine (e.g. http://www.amazon.fr/gp/product/B000J0ZRA4/ref=ox_ya_oh_product )
