[phenixbb] Crash after Torsion Angle Refinement

Dear Phenix-Gurus,

running Phenix-1.5-2 under RHEL 5, 64 bit I get the following error  
message -- this appears to occur after the actual torsion angle  
refinement. Hydrogens were added, custom-defined bonds excluded. Could  
anybody help me out, please?
Thanks,
Ulrich
