Readonly usage of fuse-zip alters archive

Originally reported on Google Code with ID 43
I am experiencing an issue where fuse-zip modifies the content of an archive even though
the readonly option (-r) is specified.

$ pwd
/home/kp
$ md5sum test.war
28ac4818756b4ca8450df846e12a1652  test.war
$ fuse-zip -r test.war /home/kp/test
$ md5sum test.war
28ac4818756b4ca8450df846e12a1652  test.war
$ cd test
/test$ cat * 1>/dev/null 2>&1
/test$ cd ..
$ sudo umount /home/kp/test
$ md5sum test.war
eed98ac92730e8ed11c144629beaa046  test.war

The md5sum has changed after mounting the archive readonly and doing a simple readonly
operation of files in the mount followed by unmounting the archive again.

When I investigate what has happened I can see that new directories have been silently
added (looks like a  duplication has taken place).

If I take a healthy version of the war-file to compare the modified against, the diff
looks similar to this:
