This is caused by a bug in the library we use to cache the SHA-256 sums for files. I wasn't able to find the root cause, so I implemented a workaround where the cache file gets deleted if we get this error when reading it. Looks like the fix was never ported to the 0.9 branch, and to be honest, it probably won't be at this point.

If you can't upgrade, you can fix the error by deleting everything in the checksum cache, which by default is /var/chef/cache/checksums
