Hi all,

Thought this should go on the list, hopefully helps someone.

It appears that if the same version of Rdiff-backup are present

but the python version differs an assertion error arises on the secondbackup ifdone a day or so later from the amd64 machine to the i386 machine. Thebackups

from the i386 machine to the amd64 machine continued without error.

Upgrading the i386 machine bellow (and removing the rdiff-backup-data dir)
to etch solved the errors.

Cheers
Gavin
