It's hard to say quite what the problem is with the small amount of
information you've included.
Certainly none of the software supplied with the OS should ever crash
with a segmentation violation, and it's definitely a bug if that
happens reproducibly.
On the other hand, segmentation faults are most commonly seen as a
symptom of faulty memory sticks. Crashes due to bad memory will
happen quite unpredictably, although they will tend to happen more
when the machine is under load and there's a lot of memory IO going
on.
If the crash you're seeing happens repeatably and always occurs in the
same place, then it must be a programming error. In which case,
please report the problem using send-pr(1). Getting a backtrace from
gdb will be helpful -- as will keeping hold of the core file you have
to make available to a developer should one request it.
Cheers,
Matthew
