OK, I've tracked the problem down to the executable inside the MacOS folder
inside the bundle. Doing a 'get info' on the original and unzipped
executables reveals the original is a 'Unix Executable File (Intel)' while
the unzipped version is a 'Terminal.app Document'. The two files appear to
be identical otherwise.

How would I go about changing a terminal document to a unix executable?
