Dear Bramha,
why are you setting the nrXX parameters by hand? Normally they are 
determined by ecutwfc and ecutrho; it is not necessary to specify them 
unless you are missing some symmetry operation, and even then only as 
little as possible.
The values yuou are (were) setting are 3 (2) times larger than the default..

Does the code work properly if you let nrXX alone?

best
