[rdiff-backup-users] IOError: CRC check failed

[Brad Beyenhof]

Hi again rdiff-backup-users,

I'm experiencing another error with my setup; a directory that had
previously worked fine is no longer doing so. Again, this is with the
32-bit CentOS 4 server (Python 2.3.4) backing up to a 64-bit CentOS 5
server (Python 2.4.3). A transcript of the error output is below.

My last problem was solved merely by removing a couple of files owned
by high-numbered UIDs out of the source directory, and hopefully
there's a similar fix here without having to manually upgrade Python
(which is likely to break other things).

I've got individual message delivery suspended for this list, so
please cc me on responses. Thanks!
