I haven't seen one of these before. XEmacs was running Gnus which was
in the middle of acquiring new mail; my mailbox had been moved to
.gnus-crash-box but its contents had not yet been split out.
XEmacs 21.2-b8, RH5.2 Linux w/2.2.1, XFree 3.3.3.1. The particular
process was quite recent; it had only been started about an hour before.
Program received signal SIGSEGV, Segmentation fault.
