[rdiff-backup-users] "OverflowError: long int too large to convert to int"

[Erik Forsberg]

Hi!

A few days ago, I started getting these errors once for each backup of
my home directory structure:

Backing up xenocide:/export/home
python: ERROR: (rs_file_copy_cb) seek failed: Invalid argument
python: ERROR: (rs_job_complete) patch job failed: IO error
UpdateError ingwa/.xsession-errors librsync error 100 while in patch 
cycleBacking up xenocide:/export/home

I got that error a few times, but didn't have time to check it
out. Now instead I get this error:

Backing up xenocide:/export/home

This happends each time I try again (i.e. even when rdiff-backup tries
to regress the failed backup).

Any ideas on this? rdiff-backup 0.12.6-1 from rpm running on Fedora
Core 1, source (ro) directory mounted via NFS, destination (rw)
directory is local ext3 filesystem. Librsync is librsync-0.9.6-0.fdr.4
(also from RPM).
