I am running phenix.refine using the graphical interface. Under "global refinement paramerters..." I am selecting "DEN".  The problem is that Python crashes all the time, always at the same point (see portion of the log output below). Is it a known bug? Is DEN incompatible with some of the options in refinement? My resolution is 2.9A by the way.

Thank you for your inputs.
