[Xuite] Fix extraction on python 3.2
base64.b64decode() accept only binary types in Python 3.2
We already do this in the CLI interface, so it should be just fine.
It worked with the GNU version, but not with the BSD version.
They catch any exception, including KeyboardInterrupt, we don't want to catch it.
