In [1]: import gst

In [2]: import gobject

In [3]:

In [3]: source = gst.element_factory_make("v4l2src")

In [4]: print source.get_channel()

(ipython:15189): GStreamer-CRITICAL **: gst_implements_interface_cast:
assertion `gst_element_implements_interface (GST_ELEMENT (from),
iface_type)' failed
Segmentation fault

So yes.

Same with v4lsrc.  This is with no v4l device present. Whatever the
reason, it's definately a bug - the python bindings should not segfault
because of this.  Someone just needs to get round to it.
