Error message for KeyError is incorrect

[sfeister]

An error message in opac-convert.py:

# Use handle_dict to create the eos_dict based on the input format. try: self.eos_dict = self.handle_dict[args.input]() except KeyError: raise KeyError('Must use valid format name.')

May assume a format name error, but this does not match the errors experienced.

Removing this try/catch revealed the actual error to be related to the subset of tables available in this particular SESAME file (only containing Total EOS), not an incorrect material format.
