Huh ? That happens on systems trying to emulate Windows' behaviour.
Grownups' system are usually Unix-based and therefore case-sensitive. And
Sage is *very* Unix-based (running a Unix VM or a Unix-like layer (Cygwin)
are currently the *only* way torun it under windows (and only the first has
reasonable behavior, notwithstanding the heroic eforts of the development
team...)).

There, you have a point ... :-) The error message below, however, *hints at
the problem in the lines that read :
"line 522, in _user raise LookupError("no user '{}'".format(username))
exceptions.LookupError: no user 'V_2e' "
