It seems that the upgrade script for 9.4 adds the category named configMoved to group property named displayMembers.
When deleting a group which has been updated by the script, a Redscreen appears. The cause is:
org.postgresql.util.PSQLException: FEHLER: Aktualisieren oder Löschen in Tabelle »o_gp_business« verletzt Fremdschlüssel-Constraint »fkb60b1ba5190e5« von Tabelle »o_property«
The method deleteBusinessGroup() only deletes the tools properties and assumes that no other properties exist.
I'm not 100% sure 
but this patch helps:
