Note that strings are immutable in Python, and if "Dict" has strings for values then the copy-by-slice is extraneous. There's no reason to make a copy of an object that can't possibly be changed. I'm pretty sure that slicing a string like that is going to return the same object anyway.
The value (not the key) is a list of strings. The strings are immutable, but (if I understand rightly) the list is not. Without the slice-copy, when I later replace one of the strings *in* the list, the dictionary's own list gets changed.
Your suggestion about whitespace sounds entirely plausible. I thought of something along that line, and looked for it with some care. But obviously I must have missed something -- and strings-with-whitespace are the only plausible Win/Mac distinction in the vicinity. If I can get at the Windows machine tomorrow I'll try to check this again.
