This has been fixed for a while in R-patched. The 2.11.1 release on
Monday should be fine.
Apparently people aren't running the betas/release candidates. You
really should run the test versions to flush out bugs. If you'd run the
pre-release versions of 2.11.0, this bug would likely have been found
before release. The standard tests can miss things; the advantage of
open source is there are many eyes looking for bugs. But if those eyes
are closed, the model doesn't work.
