CING fails to read chain with id of a space character failed by a chain with a 'A' as the id.

What steps will reproduce the problem?
Proprietary file from Wim.

What is the expected output? What do you see instead?
jd:stella/cingTmp/ cing --initCcpn logH_test.tgz -n logH_test --ipython

AttributeError: 'NoneType' object has no attribute 'ccpn'

Workaround solution: rename either chain. 

In CING chain ids can't be a space character because it would require extra 
code to work with many external programs.
The messages are reasonably clear if you can find them:
Changed chain id from CCPN [ ] to CING [A]
WARNING: Molecule.addChain: chain "A" already present
