[Duplicity-talk] tarfile: Bad Checksum

[Paul]

I created a new full backup with Duplicity. The first few nightly 
incremental updates went fine. Then last night it hung; when I manually 
killed the process, it told me "tarfile: Bad Checksum." The full 
backtrace is below.

Every time I start anew with a fresh full backup, this error crops up 
after a few nights.

Is there a way to figure out what is causing the problem? I'm running 
Duplicity 0.5.18 and GPG 1.4.6.

Thanks!
