.container in .navbar is too wide
Created by: quasipickle
As seen here (http://jsfiddle.net/dapym/1/), .container, when inside .navbar is still the full width. Adding width:auto to the .container fixes the problem (as shown in issue #1423 (closed)).
While this has the same solution as #1423 (closed), I'm seeing this at full 1280 resolution without using any of the responsive classes, so perhaps the problem is more wide-spread.
