Backup Central

I've just upgraded from 0.13.4 to 1.1.5 on a number of servers. Most
run just fine, but two of them give this assertion (below). Is this a
known problem?

Command: rdiff-backup --print-statistics --exclude-globbing-filelist
/home/rdiff-backup.exclude --create-full-path /home

I'm seeing this consistently on certain client-to-server combinations. I
ran a backup with -v9 today and the last part of the trace is attached.
Can anyone shed any light on this?

Thanks,
Keith
