Can you send us your sessionInfo(), please?

Thanks,

My .bashrc sets R_LIBS and the usual additions to the default PATH, nothing that should affect R or x11. Since I haven't heard back a flood of people saying, 'yes, me too', I suspect, this issue is specific to my setup. I've tried clearing out any preference files related to x11, to no affect. When calling plot (1:10), I get a new x11 graphics window, ten circles and an x-axis with tick-marks, and a segfault. No box(), no y-axis. There's no .Rprofile in my home directory. Are there any other preference files that could be corrupted?
