I don't understand why you are deleting this check. What notification type is
hitting the NOTREACHED?

[prasadt, 2012/02/01 22:40:31]

This method is now overridden in PanelBrowserWindowGtk class, part of this
patch. Now chrome::NOTIFICATION_PANEL_CHANGED_EXPANSION_STATE will also get
here. There is one more notification that I'll be adding in another patch
that'll also now reach here.
