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.
