I frequently get a segmentation fault error when using the "plot" command.
It happens about half the time.

We are running an old version of R (R version 2.8.0 (2008-10-20) on Linux.

I did a quick search for this problem and didn't find anything. Apologies if
I missed it.

Eventually some kind person with lots of extra time on his/her hand
will install R v2.8.0 on their machine, try to reproduce the problem,
troubleshoot it, fix the bug, and provide you with a customized
retroactive patched R v2.8.0 that you could install.  While waiting
for that to happen, you may want to try out R v2.12.2.

If the bug is in R: it looks much more likely to be in the locale handling of the X11 functions of the unstated (but probably old and unpatched) version of 'Linux'.
