The 'override path' really means to change the "view path" so that when
you click on something in the view (such as an exposed filter or a more
link) it goes to the path you specify. It doesn't change anything in
arg(0) or $_GET['q'].

I can't either. The thing to check is aliases, since aliases are the
biggest source of confusion about path. But if it's aliases I can't see
how changing the view would affect it in the slightest.

arg(0) looks directly in $_GET['q'] -- I can't imagine anything that's
actually going to change $_GET['q'] to look like music-xml when the path
is in fact music. So there's got to be something custom, somewhere,
that's doing it.
