The way to properly fix this issue was in fact to disable the registry
scanning when we import gst from the python plugin loader since...
we are 100% guaranteed this is being called from a registry scan :)
Those two lines will never be called, because caps2 will always be NULL
if we go to error (either we haven't used it yet (first goto and in this
case it's NULL), or.. it's NULL (second goto)).
This means that we take a completely new caps for the sole usage of
gst-python. The GstCaps return by gst_static_pad_template_get_caps() are
(surprise) static and therefore will always exist... as long as the
GstStaticPadTemplate (and the factory providing it) still exist.
This solves the case of getting the caps of a static pad template *before*
any element was created using the GstElementFactory. When the factory is
used to create an element, a new factory is created, replacing the old one,
and plainly discarding any static values (including those caps).
This behaviour is symmetrical to what we do at the very beginning (incrementing
the Python refcount of the wrapper object and decrementing the C refcount of the
actual object).
