Sure. But in such cases, I still add the check but give the user an
error message with as much information I can put in it. That way when
this happens later again, I can find out much more than just from a
crash. If a program crashes, users tend to just say some curses, restart
and try again. But if an error message is shown, eventually with the
hint text to contact the developers they will do that more likely.
And: a crash is a much worse user impression than an error message!
