Google App Engine Development Server DatabaseError

Question

I'm trying to run my Google App Engine App with the local Development Server I'm getting this error: DatabaseError('database disk image is malformed',)

I think the database files are corrupt. I followed this Stackoverflow post. I tried removing the temporary files at /mytemporarydir/appengine.myproject.myuser but I'm still having the problem.

I also tried run the server with option --storage_path=.... It could run (with empty datastore) but I needed sudo access and the database is not saved when I stop the server (the process is blocked).

I want to run dev server as always, without Database Error, with default storage_path and without sudo

Which file could be corrupt so I delete it?

EDIT: I also tried running the server with --clear_datastore option. I'm using Mac OSX
