Does pdb2gmx crash in both cases?

If it does, we'll need more information, including what exactly you've done to each file (i.e. show the contents) because there's an outside chance something else may be going wrong. Also, knowing your Gromacs version would be useful as well. I seem to remember a relevant bug a while back that was fixed long ago, so if you're not using 4.5.5, please upgrade and try again.

    Having never used a commercial text editor, I don't know if its integrity. 
What
    happens if you use a different editor, like vi/emacs (Linux/Mac) or Notepad
    (Windows)? What operating system are you using?

    The only times I've had pdb2gmx die when reading atom types are when the 
line
    endings are bad, so I would strongly suspect this is your issue.
