Error the index ligt buiten de matrix grenzen

Hi all, Does anyone has a clue how to solve this message.

The index ligt buiten de matrix grenzen. It happens when I try to open a detail list contact person on the relations subject. Don’t remember we changed something there.

It occurs direct when pressing the detail tab contact person. 

It’s a detail what worked for ever? It occurs in my testdatabase right after restoring a backup from live and running the upgrade.
