From email:

The development version of car 3.1-3, available on R-Forge at
<https://r-forge.r-project.org/R/?group_id=531>, produces a new error in
the broom package tests. Specifically:

We plan to submit the new version of car to CRAN in a couple of weeks,
to give you a chance to address this problem. Please let me know if
there any complications.
