[Ifeffit] Athena crash report

I checked the demeter.ini file and nor1 is set to 150. In fact, I don't see
any values ending in a trailing decimal point in this file.
I have found however that I can reliably crash Athena by opening up a
project, and trying to manually type a value (seemingly any value) for the
start of the normalization range.
