Close #94 and disables the file cache on affected PHP version

with this fix we provide a workaround for issue 94 which is caused by a
bug in PHP's unserialize/serialize implementation in all PHP versions
5.4.0 and 5.4.4. With this workaround we deactivate the file cache in
all affected PHP versions.
