[rdiff-backup-users] Debugging remote increment problem.

[David Brown]

I'm running rdiff-backup 1.1.13 on a pair of Linux machines.  One is a
Redhat enterprise machine, the other Gentoo.  I had to build python 2.4 to
get rdiff-backup to work at all.

The initial backup seems to work reliably, but increments frequently fail
with the stack trace below.

Any ideas on how to debug what might be happening here?

Thanks,
David Brown
