Are you sure that you need this block?
Extensions will be initialized in ProfileManager.
http://www.google.com/codesearch/p?hl=en#OAMlx_jo-ck/src/chrome/browser/profi...

[rharrison, 2011/05/19 00:31:43]

Since we are not in a proper logged in browser I don't think that the extensions
will be enabled, since right above in the ProfileManager it tests if we are
logged in. This was done to allow the keyboard to be used. If there is a
preferred way to do this I would like to know about it, since this seems a bit
hacky to me.

[Nikita (slow), 2011/05/19 03:53:33]

Let's clarify 2 things:
1. Is keyboard extension a component one? I think that's the case.
If it's not, it should be. 
2. As you could see in ProfileManager, in case if we're not logged, only
component extensions should be enabled. That's all you need. So you should
remove this code and check that keyboard would still work.

if (!logged_in_ &&
      (!command_line.HasSwitch(switches::kTestType) ||
        command_line.HasSwitch(switches::kLoginProfile))) {
    init_extensions = false;
  }

Also you're checking whether profile is incognito one, it will be (as it is a
pre-logged in state). I'm not sure what fetching original one would return in
that case, have to check code.

In either way, component extensions initialization that you need should not be
handled in this place.

[rharrison, 2011/05/19 16:45:28]

I think it is a component extension. I misunderstood how extensions are
initialized. You are correct, I shouldn't need this hack. I will remove it and
test that everything sets up correctly.

It's touch specific while it shouldn't be.
Since we'll be reusing this (a bit refactored) class for non-touch builds with
WebUI too, please take that into consideration in future CLs.

Please at least  place a TODO here and hide all keyboard related code under
TOUCH_UI define in future CLs.

Generic question: are you planning to have UI language selection control
somewhere in the WebUI login implementation?

In current views implementation it is placed at the new user pod which is not
applicable in case of GAIA Web Auth.

[rharrison, 2011/05/19 00:31:43]

I had not thought about it. I think we will have to figure out how to handle it
correctly.
