weird, this doesn't match the GitHub bower.json. but it's not pulling down this
mysterious non-existent file, so looks okay I guess

That is indeed weird. I double checked that when doing
bower install --save polymerelements/paper-listbox

the bower.json that is checked out does not match the Github bower.json.
Guessing that this is an issue on their bower setup.
