If you use --script it will return a 1 in this case.

I agree, somewhat, but it would be difficult to squash parted's normal
exception handling for cases like this. Note that it *is* output on
stderr so if you don't want to capture it just grab stdout. And if you
use --script it will return a proper error result code.
