    Bug 41043: Hardcode the UI font on Linux
    
    The mechanism to choose the UI font does not play well with our
    fontconfig configuration. As a result, the final criterion to choose
    the font for the UI was its version.
    
    Since we hardcode Arimo as a default sans-serif on preferences, we use
    it also for the UI. FontConfig will fall back to some other font for
    scripts Arimo does not cover as expected (we tested with Japanese).
