[BioPython] error in writting pdb file

[Bala subramanian]

Dear Friends,

When i try to write a pdb file with PDBIO, i get the following error. What
could be the possible reason for the same.

>>> out=PDBIO()
>>> out.set_structure(s)
>>> out.save("new.pdb")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File
"/home/bala/Desktop/biopython-1.49/build/lib.linux-i686-2.5/Bio/PDB/PDBIO.py",
line 150, in save
  File
"/home/bala/Desktop/biopython-1.49/build/lib.linux-i686-2.5/Bio/PDB/PDBIO.py",
line 84, in _get_atom_line
TypeError: %c requires int or char

Thanks in advance,
Bala
