Re: [rdiff-backup-users] OverflowError when backing up remote server

[Ryan Castle]

I don't know much about Python, but it appears that FileObject.read()
expects an integer, and in your particular the instance the size data is
large enough that it won't fit into an int. I think that must mean that
the data length is over 4gb cause that's where python ints seem to end.

Even if the data should never get to this size, if would be good if the
code didn't depend on the implicit cast from long to int.
