Apart from William, who is quite busy, can we add someone in cc who knows
about Numpy and/or Lapack?
If we could get some more precise details about how it's been isolated, we
might be able to post to the Numpy list now.

I'm not sure that achieves anything useful. Sure the doctest will pass,
but it might actually delay the urgency given to fixing the underlying
problem. A successful test is one that has uncovered a previously unknown
error. This tests has done that. I don't personally think it's appropriate
to water down the test just to get 100% passes.
I suggested some time ago we should have a page on a wiki which documents
known issues with a release - either before or after the release is made.
e.g I started this, though it's not been updated
http://wiki.sagemath.org/errata
I think it would be better to document the problem rather than temporarily
hide it.
