Duncan *did* say that he was using  R 2.12.0. So that's not likely
to be the problem. Most of the time, when users claim that a
problem exists in a new version that did not exist in an older
version, it's due to a change in the user's setup or to not
updating packages or to not checking the NEWS file.

Since you still have not provided a *reproducible* example,
it's not likely that anyone can help. Can't you make up a
small example that shows exactly how you are using lm()
and that will generate the error?
