[rdiff-backup-users] rdiff-backup 1.2.5 and Python 2.5.2 CRC Check error

[Brian C]

Backup server (named 'tempe') cannot backup other server (named '1080amg'
and at 192.168.1.35) because of lengthy Python 2.5 error (pasted below).
Both servers run Debian Lenny. Thanks for any help. I have also seen
python segfault in syslog on this server, and reported that here:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=526029

Error:

Previous backup seems to have failed, regressing destination now.

IOError: CRC check failed
Fatal Error: Lost connection to the remote system

On both servers:

# rdiff-backup -V
rdiff-backup 1.2.5

# python -V
Python 2.5.2

Any ideas?
