Hi, all!

I try to use density fitting in TDDFT calculation of naphtalene (D2h sym), with following input
title "naphtalene TDDFT UV/Vis"

memory stack 100 mb heap 100 mb global 2000 mb

geometry
 symmetry D2h

When I set symmetry to C1 I get a normal result (same as without CD fitting).
What's wrong with symmetry?
