If I was looking at an error like that, I'd get mighty annoyed with the software, and after a while would definitely look for alternatives. Whether or not there's a coding problem, you have to look at the situation from the point of the user: a complete failure with no information is like a BSOD/TSOD ... and we all know the effect they have on a user.
