What version of R, platform, loaded packages etc? This is not what I see
on Linux, 2.9.1-patched r49104.

Have you tried this in a clean session to see if it persists there?

If you can reproduce this in a clean session with an up-to-date R or
R-Devel then send details of your R back to the list for further
investigation.
