Sorry apparently I made a mistake, the index that I fixed was a dir that I
copied outside the app directory.. The 'new' database with index dir emptied
certainly works, as it has no index on the data
Once I copied back the repaired /index folder, it still show the same error

So far the only way to get the database accessible is only by removing the
index folder.
Cheers,
