I think this is caused because the interpolator gets notified of a new group being added as soon as that happens, but before a new label has been added to the group. When trying to update the interpolation, it tries to get the value of the active label inside QmitkSlicesInterpolator::OnInterpolationActivated(), which causes the error because there is no active label set.
