The following program results in an ArrayStack with an ArrayStack with two Objects and a null element when it should end up with an ArrayStack with three Objects.

import scala.collection.mutable.ArrayStack
var x = ArrayStack[Object](new Object, new Object, new Object)
x filter (_.isInstanceOf[Object])

This seems to be fixed in both 2.10.0-RC1 and 2.11.0-20121010-013641-9bedb07350.

I'll leave it open for those who decide whether there will be a 2.9.3.

Test case in scala/scala#1733. I'm not sure when it was fixed, it was sometime in v2.9.2...v2.10.0-M1.
