As far as I understand it in DISLepton::project the iteration over all vertices and fails on the vertex "-6", because there are two outgoing leptons ("10009" and "10015"). The first electron loops over vertex "-5" back into vertex "-6" (for what ever reason), so it is not an actual final state particle. The old code from version 2.5.3 does actually work for the event.
