Looks like you just copied this value from the webstore app - for chrome
extensions/apps, the key is actually per-item, not a certificate used to sign
multiple different items. So you should generate a new random key to use. To do
this, just create a dummy empty extension, use the chrome://extensions page to
pack it into a .crx file, install that, find it's id on the chrome://extensions
page, and then look in your <user profile dir>/Preferences file to find the
entry for that extension and copy the key value out. Also that id should be the
value that you use for the kChromeAppId constant. 

(Sorry this is such a hassle - we don't need to do it very often or otherwise
we'd make it easier).

Actually, this is a different key from webstore. :) I followed your steps to get
this key created. It just happened to be the same on the first 39 chars.

The last 7 characters too! That defeated my typical "eyeball the difference
between two long hashes by looking at the first few and last few chars"
algorithm. =)

Instead of http://www.google.com/chrome, can we make the url be something like
http://DUMMY-VALUE or http://THIS-WILL-BE-REPLACED?

Also can you please add a comment here that mentions that this will be changed
by special case to become chrome://newtab? (Our json parser supports c-style
comments with a leading // delimiter).

Done.
