Sorry, what I'm trying to say is that I think gst_bin_new() should use
g_object_new() to create a GstBin because it makes it possible for the c++
bindings to create these bins by using standard glue code in c++ constructors
using g_object_new().  I hope this is not a superfluous bug and that I'm not
mistaken in this report, but the "Exporting a C API" chapter of the GObject
manual ( http://library.gnome.org/devel/gobject/2.17/ch01s02.html) explains
that the purpose of the GObject functionality is to allow automatic glue for
bindings easier:

"The greatest advantage of the solution implemented by GType is that the glue
code sitting at the runtime domain boundaries is written once: the figure below
states this more clearly."

"Although that goal was arguably laudable, its pursuit has had a major
influence on the whole GType/GObject library. C programmers are likely to be
puzzled at the complexity of the features exposed in the following chapters if
they forget that the GType/GObject library was not only designed to offer
OO-like features to C programmers but also transparent cross-language
interoperability."

Is there something I'm misunderstanding?  If it's possible to do the same thing
using a few extra function calls this would be nice for the c++ bindings (I'm
pretty sure).  Thanks.
