I would say generally no. They are uncommon in general but when they
happen they happen in bursts. As a general rule I think we should strive to
make what the user sees be something a lot more friendly than a wild stack
trace. But, the logs should have them. We did discuss this on dev list a
while back and there were some great inputs from various folks. We def need to
do something here.
