I've run into this several times, but I thought Dan mentioned once that the problem was really that string registers should never be NULL. Which sounds good to me, since it speeds up and simplifies various things, for example the JIT. On the other hand, it would still make sense to check in the string functions, since there will be many ways to end up there. I might just be making stuff up, too.
