Hi Pavel,

What version of rdiff-backup are you running on the remote end? I just  
want to be sure that it is 1.1.15 as well.

Actually, I think this is a new error. You are seeing "[Errno 22]  
Invalid argument" from that call, whereas in the past, I have only  
seen "[Errno 45] Operation not supported" or "[Errno 1] Operation not  
permitted", both of which are now handled cleanly.

To add your new error to the list of "don't fail on this" errors, go  
to eas_acls.py. You should see a test around line 110, which has:

if exc[0] == errno.EOPNOTSUPP or exc[0] == errno.EACCES:

change to:

if exc[0] == errno.EOPNOTSUPP or exc[0] == errno.EACCES or exc[0] ==  
errno.EINVAL:

and you should be good to go! The code in question should have a  
comment immediately above it that says:

# Mac and Linux attributes have different namespaces, so
# fail gracefully if can't call setxattr


let me know if it works,
Andrew
