There is a corruption into index when I tried to obtain an object that non exist into database. This was soluted with "doctor"

Thank you for this report and for the update.

You closed the issue, as the the database was fixed with the Doctor, but if you have more information about the cause of the index corruption we will be happy to explore this issue further, especially if it happens again. Of course, if you find a way to reproduce index corruption it may be of a great help.
