throws CodeGenerator NPE where I expected a JS ReferenceError #110

I'm running current git master. This is the simplest testcase I could find:

[foo.bar.id] = true

(I noticed that when I remove the last property access - [foo.bar] = true - I get a ReferenceError as expected)

Due to Cannot invoke "org.mozilla.javascript.Node.getType()" because "node" is null

Still happens on master
