Something in one of your atom objects isn't as expected.  The
_get_atom_line code is trying to construct a string for an atom line
for the PDB file, but one of the strong formatting arguments isn't
setup right (the TypeError about %c).

Without seeing how you constructed the structure (variable s in your
code) its hard to guess what is wrong.  Maybe one of the required
properties is set to None?
