[rdiff-backup-users] rdiff-backup failure

[Stuart Robertson]

My rdiff-backup between mac os 10.7.2 client and freebsd 8.2 server has failed and I don't understand why. Client 1, 10.7.2, and Freebsd 8.2 were working and a different client and the same server are still working (client 2 is mac os 10.6.8). On both clients rdiff-backup is 1.2.8 installed with macports. The server rdiff-backup is the port of 1.2.8

The end of the failed verbose log is below (the full log is hundreds of lines).

How do I find out what is wrong?
Any help appreciated,
