js2-mode crashes with "wrong-type-argument: stringp, nil" error

[GoogleCodeExporter]

The following line, by itself, triggers the error above:

Cu.import("resource://gre/modules/XPCOMUtils.jsm"); // for generateQI

It fails in js2-parse-highlight-prop-get, and with a bit of debugging, prop is 
[cl-struct-js2-name-node 39 9 0 nil [cl-struct-js2-prop-get-node 33 0 9 nil 
[cl-struct-js2-call-node 38 1 50 nil nil #1 ([cl-struct-js2-string-node 41 10 
39 nil #2 "resource://gre/modules/XPCOMUtils.jsm"]) 9 49] 3 
[cl-struct-js2-name-node 39 0 2 nil #1 "Cu" nil] #0] nil nil]

Ironically, there's a comment in js2-parse-highlight-member-expr-node (the very 
next function) that tries to make it robust against node names occasionally 
being nil, but a similar fix wasn't made for prop names.  The following patch 
fixes things for me:

diff js2.el js2.el~

Hope this helps...
