The exact same problem has been reported to me with 3.1 on Fedora's
Bugzilla :
https://bugzilla.redhat.com/show_bug.cgi?id=543660

- from the web interface, if you try to get a zip file to restore with a
compression value > 0 ; you'll get a wrgon empty zip file.
- from the web interface, if you try to get a zip with compression=0 ;
you'll get a valid file
- from the command line, all goes well, with any compression level (so I
guess this is not a missing perl module)

There is no error message anywhere, and I do not know which args are
passed to the command from the web interface.
That should be a problem to debug the issue, so if someone could tell me
what to change in the code to get some message helping on debug I should
maybe produce more detailled error (sorry, but I do not know perl :( ).

Regards,
Johan
