I would suggest that dpkg detects the error and brings back the package state to half-installed forcing the package manager to unpack it again. It seems to me that the error code ENOEXEC is sufficiently specific (and it could be associated to a check of the file length if needed) for this to be reasonable. BTW, I think it would have been wise to include the upstream dpkg maintainers in the discussion from the start, you're lucky that I'm following ubuntu-devel... We would also be glad if some people could volunteer to triage dpkg bugs on launchpad and make sure we have everything filed in the Debian BTS.
