Re: [rdiff-backup-users] Assertion error when restoring files

[Ryan Castle]

We get that problem. We've had it since 0.13.2 I think. Not sure what the 
solution is. It seems to get into certain directories and then not be able 
to get out. To get it working I commented out the assert line. That's not 
ideal, but it's been working for us for several months now. My python isn't 
good enough to write a fix. :)
