FlexPepDocking.mpi.linuxgccrelease bails out ERROR: total_residue() != 0 ERROR:: Exit from: src/core/pose/Pose.cc line: 1369

When I tries to use FlexPepDocking it bails out ERROR: total_residue() != 0. Though I have been able to use the same pdb file with the web server. It appears that FlexPepDocking generate a pose that do not contain any residues and that the assert statement in Pose.cc bails out due to this reason. Is there anything wrong with my pdb file, I have also tried to include a co-factor which is parameterized. This error appear but with and witouth any co-factor.
