New description:
1. The output of `GeneralDiscreteDistribution().get_random_element()` is
not a Sage number per se and hence has no `parent` attribute.
2. The import of sage.rings.real_double seems unnecessary in the file
`devel/sage/sage/gsl/probability_distribution.pyx` since all the calls to
RDF are made explicitly as `sage.rings.real_double.RDF` in the entire
file.
Attaching a patch to fix both the above issues. The patch passes all
doctests in `devel/sage/sage/gsl`.
----
Apply [attachment:trac_12498-return-Integer-from-
GeneralDiscreteDistribution.2.patch] to `devel/sage` of sage-5.0beta10
