Comment(by nicklas):

 You are right strk, it might be something we cannot control.

 But there is some strange things happening here, which I don't really
 understand.

 I will try to add a test case showing the effect.

 The question is if can detect if there is no working index and in case of
 that I think we shouldn't use prepared geometries in those cases.

 I will try to make the ticket more complete.
