dock apps with spaces in the App name don't work

For instance, for google chrome I get the following:

failed: [localhost] => (item=~/Applications/Google Chrome.app) =>
{"changed": true, "cmd": "PYTHONIOENCODING=utf-8
~/src/github.com/kcrawford/dockutil/scripts/dockutil --add
~/Applications/Google Chrome.app ", "delta": "0:00:00.038487", "end":
"2014-07-03 10:35:56.220356", "item": "~/Applications/Google
Chrome.app", "rc": 1, "start": "2014-07-03 10:35:56.181869"}

stdout: Chrome.app does not seem to be a home directory or a dock plist
