Re: [rdiff-backup-users] KeyError: 'xattr'

[Kevin Fenzi]

Greetings. 

Forgive me for opening an old thread, but I am seeing this problem here
as well...

I am one of the maintainers of rdiff-backup in the Fedora linux
distribution, and we have had reports of this issue there as well. 
I also have been able to duplicate it here on a machine of mine. 

Removing python-pyattr works as a workaround, but doesn't seem to me to
be a solution. ;( 

You can find more info about the bug at: 

https://bugzilla.redhat.com/show_bug.cgi?id=465574

My setup here that I can duplicate on is a Fedora 8 machine with a JFS
partition. Running either 1.2.1 or 1.2.2 of rdiff-backup I get
tracebacks like:

Happy to provide more info or debugging to get to the bottom of this
issue.
