Slepc interface problem, IPNorm: The inner product is not well defined!

I have a generalized eigenvalue problem where B is a singular
matrix(rather more problematic there are some columns and rows with
zeros due to a finite element modelling issue.). I read section 3.4.4 of
slepc manual on the purification, however i could not understand much
about the details. But I guess, I should use as problem type,
EPS_PGNHEP, however, I am still getting a "IPNorm: The inner product is
not well defined!" error. Can someone/developers shed some light on this?
