Convergence problem

Hello gnucap fans,

I have been trying to run this simple circuit using a SPICE BFR92A  NPN 
  model from Philips. It runs ok on Ngspice but on Gnucap 2009.12.07 RCS 
26.136 I have a convergence problem:

tried everything, still doesn't work, giving up

Any tips to make it work will be welcome. I do not know what I am doing 
wrong.

Thanks.
