[Bug 1429939] [NEW] zipinfo crashes without arguments

[Egmont Koblinger]

Public bug reported:

In Trusty, "zipinfo" or "unzip -Z" printed its usage (it looks
suspiciously wrong, e.g. with some invalid UTF-8, but anyway it
survives) and exits cleanly (with exit code 0).

In Utopic, the same command prints some usage info (probably not
everything it wishes to print), and then crashes with the message
"error:  zipfile probably corrupt (segmentation violation)" and returns
with exit code 3.

This causes problems e.g. for midnight commander's configure script
(Ubuntu's mc has a workaround for it, but this bug is the root cause,
and I'd like to compile mc myself for other reasons).
