[rdiff-backup-users] Integer too small on AMD64 machine

[njbailey]

Hi,

I've been trying to use rdiff-backup to copy between two locally mounted disk
drives on a AMD64 box running Ubuntu. After creating about 16BG of files in the
destination directory, the command fails with an integer overflow error.

Is this a 64-bit problem? I don't see anything in the FAQ or Wiki which might
help out.

I'm using python 2.4.1, librsync1 0.9.7 and rsync 2.6.3-2ubuntu1 packages.

Interested to know if anyone else is experiencing this problem.
