Dear All

Please find below my errors

I suspect this might be a known issue with the current index
implementation. If so, then --clear(ing) your index should fix the
problem, but then the next save will be much more expensive than usual
because bup will have to rediscover the hashes.

I've been hoping to finish a possible index overhaul for a while, but
haven't yet had enough concentrated time.

Sorry for the trouble.

Hi,

Just saw you also emailed me - I guess you found out list was quicker to
get a response ;-)

Agree with Rob, this is likely a corrupted index somehow. Not sure how
that'd have happened, but it's clearly in the metadata.py while reading
the posix1e acl, and since it was save, that must've been the index.

Not exactly sure what that is, but also not sure what version exactly
you're running.
