Comment 3 for bug 883971

noticed this trying to read an nfs mounted fusecompress shadow-dir mounted locally where the source was 11.04 and the client is 11.10 -- same error, I suspect the same cause -- this is a pretty unacceptable risk here, that a minor-version upgrade would instantly render any stored data as irretrievable!! people need to be warned: can someone call FOX news? :)

my 'fix' workaround to retrieve the data: find a prior version machine, export your fusecompress shadow-dir and mount over nfs, then mount that shadow-dir on the client under the previous version (ie 11.04) and quickly backup your data.
