[rdiff-backup-users] Crash whilst regressing file

[Olly Stephens]

Hi,

I've been running rdiff-backup for a while now to backup a remote server 
to a local NFS mounted disk.  It's all been working fine.

But recently a backup failed and any subsequent attempts result in the 
crash detailed below.

I've upgraded both servers to the latest version now but at the time of 
the failure they were running the default versions that came with debian 
(which was something like 0.13 on the remote host, 1.0.3 on the local)

Anyone have any idea what's wrong?

Thanks in advance

Olly
