[rdiff-backup-users] rdiff-backup-1.1.5 can't use earlier rdiff-backup backups

[Sebastien Maret]

I've just upgraded rdiff-backup from version 1.0.4 to version 1.1.5 on both
server and client side. Now when I list the increments of the backup I've
made with the earlier version, I obtain the following error:

% rdiff-backup -l server::/path/to/backup

Fatal Error: Lost connection to the remote system

I've tried to make a new backup on the server and it's works fine. Are
the backups done with earlier versions of rdiff-backup imcompatible with
rdiff-backup-1.1.5 ?

I am using rdiff-backup-1.1.5 installed with Fink on MacOSX 10.4.4.
