Now I have. The computer is my laptop and not connected to the net so I can't upload details, but R-1.2.1-patched as of yesterday does NOT exhibit the same bug. So I guess you are right. Sorry for wasting your time. I'm still a newbie at this R stuff. Next time I'll check against R-*-patched before submitting a bug report.
