Hi,

rdiff-backup is failing while testing if your filesystem supports extended attributes. I know the development version (1.1.15) supports skipping this test if you run with the --no-eas option, but the 1.0.5 version does not. You will need to make the xattr module unavailable to avoid the test (or comment it out).

On a side note, it is strange that rdiff-backup is failing at this point. What this means is that the following situation occurred:

- rdiff-backup successfully imported the python xattr module for extended attributes support

- a listxattr(path) call succeeded without raising an error, suggesting that extended attributes can be read

- a setxattr(path, "user.test", "test val") call succeeded without raising an error, suggesting that extended attributes can be set

- a getxattr(path, "user.test') succeeded without raising an error ... but it did not say that "test val" was the value of that attribute!

Has something changed in your system setup?
