proposed patch

If a user has his/her own installation of pygobject and pygtk, the Python
plugin loader in plugin/gstpythonplugin.c will load the gobject module found in
the top-level site-packages directory, instead of the user's version of
gobject.

In Python modules, it appears to be common practice to import gobject using the
following recipe:

import pygtk
pygtk.require("2.0")
import gobject

And doing this causes the user's version of gobject (which would be in a
site-packages directory that occurs earlier in sys.path) to supersede the
top-level site-packages directory.

This is, in fact, what is done in the "gst" module's __init__.py file.

This practice is also mentioned on the following two pages:
http://gstreamer.freedesktop.org/wiki/FAQ#Mypygstprogramismysteriouslycoredumping.2Chowtofixthis.3F
http://faq.pygtk.org/index.py?req=show&file=faq02.004.htp

The attached patch adds a C equivalent of this procedure to gstpythonplugins.c.
 It does result in the "correct" version of gobject being loaded.
