Default Adobe doesn't know how to zip EPUBs

I've been running into strange problems.
All of the e-books that I borrow from my public library have problems.
(This problem also occurs downloading EPUBs from Adobe's demo site.)
Sometimes my Library.apk can't find the e-book's metadata.
It usually works fine on the Nook, but the JellyBeans have problems.
This has to do with the unzipper in Android.
The older unzipper was more resilient to failures.
The newer unzipper bombs on errors.

Quite simply, the EPUBs coming out of Adobe Digital Editions (versions 2.0 or 3.0 for Windows) zip EPUBs incorrectly.
META-INF/container.xml and OEBPS/content.opf have zeroes in the Local Header for the fields of crc, size1 and size2.
Additionally, some EPUBs have garbaged filenames in the Central Directory.

To fix, you can unzip and zip the files without changing the DRM.

Has anybody else noticed this?
