prototype1.7 conflict

There is no V8 bug.
Closure library expects that it can apply Array.prototype.filter to objects
that behave like arrays but do not necessarily have Array.prototype as in
their prototype chain. See for example:
http://code.google.com/p/closure-library/source/browse/trunk/closure/goog/array/array.js#234 .
ECMA-262 intentionally specifies Array methods in a generic way to allow
such kind usage.
Prototype however monkey patches Array.prototype with his own methods
(including filter) which do not follow this ECMA-262 specification and
expect that receiver will have Array.prototype in the prototype chain. It
replaces Array.prototype.filter with it's own findAll function:
https://github.com/sstephenson/prototype/blob/master/src/prototype/lang/enumerable.js#L299
which does not work for arbitrary array-like objects that do not have
Array.prototype in the prototype chain.
Thus this is exception is fully expected.
