This suggests that it's reasonable for a program to segfault because the user made a mistake, instead of having some non-fatal form of error handling. I don't think that should be acceptable at all, though I agree it's very common. If I had a dollar for every time I've lost work because a segfault or GPF happened before I saved my document...
