Re: [rdiff-backup-users] problem with restore

[Ryan Castle]

Hi,

I've had that problem in the past. A very doubtful solution was
commenting out the lline in restore.py that checks for the assertion.
I read some of the code, but was never able to work out what the
assertion was for. Though presumedly it is useful. :)
