Backup fails after initially scanning older backups

[Neil Robinson]

This problem has only surfaced since upgrading to 11.10

Expected result:
Backup backs up files to external hard drive as it has previously done flawlessly.

Action taken:
Run deja-dup.
Select make new backup.
Scanning starts, but stops and deja-dup reports "Backup Failed."

Gives this error:
Failed to read /tmp/duplicity-Xxfwll-tempdir/mktemp-8Ylyy0-1: (<type 'exceptions.IOError'>, IOError('CRC check failed 0x96cdfab != 0x8652a9f7L',), <traceback object at 0x86fcb44>)

--

Incidentally, it restoring backups from the previous backups results in a similar error.
I haven't tried restoring anything using duplicity directly.

Tried a new backup to another folder location, and that works fine.
