It means that something went wrong trying to unpack a ZIP archive (such
as an MCZ file, which is in ZIP format). The error message is slightly
less horrible in images after 4.6.

Occasionally you may have an empty or corrupt file in your ./package-cache/
directory that leads to this error message. If so, you can just delete
the contents of your ./package-cache/ and things will return to normal.

If you happen to be running your 4.6 image in a different directory
than other images, then it may appear as if the error condition is
associated with that version of the image.
