Test application

I haven't been able to make any python applications work with 0.11 lately. I get errors as seen bellow, talking about stuff not being initialized. The attached test application used to work fine for me 3-4 weeks ago. 

python gst-gi-test.py
Traceback (most recent call last):

Comment 1 Edward Hervey 2011-11-21 10:58:53 UTC 
Same old issue of having to set (transfer none) instead of (transfer full) for methods returning a newly created floating object.

Find the relevant bug in gobject-introspection and/or pygi and mark this one as a duplicate of the other one.
Comment 2 Tim-Philipp Müller 2011-11-21 11:06:48 UTC 
There's bug #657202 and bug #656205 . It needs to be fixed in pygi.
Comment 3 Christian Fredrik Kalager Schaller 2011-11-21 11:26:12 UTC 

*** This bug has been marked as a duplicate of bug 657202 ***
Comment 4 Christian Fredrik Kalager Schaller 2011-12-12 11:47:56 UTC 
Re-opening, because even if the upstream gobject-introspection bug in 657202 is fixed, we still need to do this annotation in GStreamer 0.11
Comment 5 Tim-Philipp Müller 2011-12-12 12:16:35 UTC 
Hope this fixes it (didn't test myself since I'm still on g-i 1.31.0):

    elementfactory: use new 'transfer floating' annotation for gst_element_factory_make()
    
    Requires gobject-introspection 1.31.1 (older versions will
    error out with that).
