sqlite3.OperationalError: file is encrypted or is not a database

According to Dustin, this is because the mbrestore tool does not currently support WAL db files and the workaround is to run: /opt/membase/bin/ep_engine/management/sqlite3 <filename> 'pragma journal_mode=delete' on all the db files you are trying to restore.

Please add the above workaround to the mbrestore script itself.
