Have you registered a "close" function for your storage, too?

The API is a bit inconsitent:

  While you open both a storage and a DB, the "DB.close()" implicitly
  closes the storage as well.

  Thus, if you have registered a "storage.close", the "DB.close()"
  might find the storage already closed and get an error as you
  reported.
