apparently the previous fix doesn't actually get us past the error;
this one should do a better job although it's still not perfect
either. for some reason the redirect to 'home' route is confused such
that it the new URL drops the ending filename but the rest remains, so
it's not really the home URL.. oh well at least this is better than
before
what i've seen in the wild seems to be caused by a crawler trying to
fetch non-minified JS files, when the fanstatic resource library only
includes minified JS files. still not sure why that would cause the
specific error but oh well, this hopefully "solves" for now
