[Duplicity-talk] Incompatibility betw. v. 0.4.x and 0.6.x ? - Was: Re: Fails to restore backup : AssertionError: [(('bin', 'gunzip') reg)] :-(

[Olivier Berger]

Hi.

I suspect I have experienced an incompatibility problem between backups
made with a Debian stable system (v. 0.4.11) that I tried and restore
using a Debian testing system (v. 0.6.06).

Are there any incompatibilities between these versions ?

Thanks in advance.

Best regards,
