Re: [rdiff-backup-users] OverflowError when backing up remote server

[Jon Daniels]

Okay, it appears that rdiff-backup is seg faulting on the remote server
(RH Linux).  I've tried upgraded to Python 2.3.3, re-installing librsync
and rdiff-backup, and I've tried the development version of rdiff-backup. 
No matter what, it always seg faults.  Python seems to work fine.  I could
have sworn it was working yesterday....

What could be causing a segmentation fault of rdiff-backup?
