Delete the file /var/lib/tarsnap/cache/cache. It got corrupted somehow
(most likely truncated due to the OS crash) but will be regenerated
automatically. (This is the file which says "the last time we looked at
file /foo/bar, it contained blocks X, Y, and Z" -- without this file you
will have extra disk I/O and CPU time as Tarsnap re-examines everything,
but that's all.)

I have an astonishing mess of namespace collisions. Deleting archives needs,
and fsck reconstructs, the *directory file* in the cache directory. The
problem you're running into is with the *cache file* in the cache directory.
Clear as mud? ;-)
