>From the documentation of gst_pad_set_caps (pad, caps):
"It is possible to set NULL caps, which will make the pad unnegotiated again."

It seems to be impossible to do this from Python:
>>> import pygst; pygst.require ("0.10"); import gst
>>> pad = gst.element_factory_make ("fakesink").get_pad ("sink")
>>> pad.set_caps (None)
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
TypeError: could not convert to GstCaps

Attaching a patch that allows for that.
