[PyMOL] segfault when loading sdf files

Hi, I am using pymol from the SVN, and I have run into a problem when 
using revision 4083.
When loading an sdf file of small molecules, pymol segfaults with the 
following error:

/usr/local/bin/pymol: line 3: 29872 Segmentation fault      (core 
dumped) "/usr/bin/python" 
"/usr/local/lib/python2.7/dist-packages/pymol/__init__.py" "$@"

I don't get the error when I revert to revision 4082.
The diff indicates that the error is in the ObjectMoleculeSetDiscrete 
function in layer2/ObjectMolecule.c

Thanks,
Matt Baumgartner
