Description Mark Nauwelaerts 2008-06-25 21:18:16 UTC 
See interactive session below.
Problem only occurs if the returned value is NULL
(and may affect other GstMiniObject based types as well).

Might be due to the pygobject, or to gst-python.

>>> import gst
>>> f = gst.element_factory_make('filesink')
>>> b = f.get_property('last-buffer')
Traceback (most recent call last):

it's a bug in gst-python. The registered type conversion from miniobject GValue to Python type would return NULL if the GValue contained NULL.

A proper fix would be to return None (no object).

	* gst/gstmodule.c: (pygstminiobject_from_gvalue):
	Return None if GstMiniObject GValue doesn't contain anything (NULL).
	Fixes #540221
