--- Comment #1 from Tim-Philipp Müller <t.i.m at zen.co.uk> 2013-01-05 17:17:01 UTC ---
Curious, but I'm not sure if this is a bug in gst-python, rather than
gobject-introspection or pygobject.
As a work-around you can do this btw:
>>> src.set_property('format', 3)
>>> print src.get_property('format')
<enum GST_FORMAT_TIME of type GstFormat>
Stack trace for the warning:
$ G_DEBUG=fatal_warnings gdb --args python
(gdb) run
Python 2.7.3 (default, Sep 9 2012, 17:41:34)
>>> from gi.repository import Gst
>>> Gst.init(None)
[]
>>> src=Gst.ElementFactory.make('appsrc',None)
>>> src.set_property('format', Gst.Format.TIME)
** (python:29952): WARNING **: expected enumeration type GstFormat, but got

This may not be the latest version of gi/pygobject, but I didn't see any
commits in git that look like they might have fixed this (but I didn't look
very hard).
