 In testing the updater using the candidate 4.0a2 builds, brade and I found
 a problem that causes the update to silently fail.  On the browser
 console, we see:

 {{{
 [15:20:56.361] WARN addons.manager: Exception calling callback:
   TypeError: self.update is undefined @
 chrome://browser/content/aboutDialog.js:439
 }}}

 It looks like we used self.update in a couple of functions where we should
 have used this.update.  I am not sure why these code paths were not
 exercised in our earlier testing, but we are working on a fix right now.

 If it is not too late, we should respin 4.0a2 to pick up this fix.
