OverflowError while restoring a backup (ecrypted/local repo)

[Socket]

Duplicity version: 0.6.22 (from tar.gz downloaded http://duplicity.nongnu.org/ )
Python version: 2.7.3
OS Distro: Kali Linux 1.0.5 32-Bit
Type of target filesystem: Win 7 NTFS (actually I'm doing the restore via a VM with both repository and destionatio are mounted as shared folders--vboxsf. I preferred this setup because using cygwin I had other exceptions related to fork() and such)
Description: While restoring a backup from a local repository, encrypted with gnupg, i got "OverflowError: Python int too large to convert to C long".

Being this information quite urgent I'm asking whether there is a "manual" way to retrieve whatever contained in the backup.
