This shit is severely outdated, I haven't had the time to check out what works and what doesn't as I am working on 0.9 release.

Mainly two problems at the moment which stops extension from running: chrome.extension.onMessage in background doesn't work, and chrome.storage in content scripts is not yet supported (but will be according to the bug tracker).
