Two points:

  1. yes, please alsways specify a simple reproducible example when talking about a "bug";
  2. if this "bug" does not appear in R-2.0.1 but only in the current R-devel, it might be worth to wait a couple of days. Perhaps someone is including some new functionality and has not yet finished the updates.
