RE: [rdiff-backup-users] UnboundLocalError on Windows XP

[Mark Hubbard]

Thanks for following up guys.  As it stands now the program does end
when it hits this exception, so it's a show-stopper.  That's a shame
too; I think this program is the silver bullet for my personal needs.
It's a real beauty.  I'll keep my eyes open for an updated binary, since
I have very poor luck getting most open source projects to compile/run
from source.

Oh well, I'm off to contribute to the avrdude project for now...

Mark

Actually, the "can't retrieve ACL" error messages are related. The error

you are seeing is a bug in rdiff-backup that happens when, for whatever,

reason, rdiff-backup is unable to retrieve ACL's (i.e. permissions 
information) for a file. The solution is to simply log the error (which 
we're doing now), and continue. I've committed a fix to CVS for this.

Andrew, could you please review this fix, then backport to the stable 
branch?

Thanks,
JoshN
