Well, R-2.13.0 is in "Release Candidate" ('RC') stage, after having
passed the alpha and beta stages.

So, almost surely, the current CRAN version of Matrix, also part
of all recent R-2.13.0 tarballs will be shipped along.

If we can reproduce your problem, we will fix it, hopefully
pretty soon, and release a version of Matrix,  0.9996875-0
close to the release time of R-2.13.0;
but for stability reasons (of R-2.13.0 and all its testing on
all platforms), it would not ship with 2.13.0 and only people
who explicitly update.packages(...) [after R-2.13.0
installation] will get it.
