[gtranslator: 1/2] Fix loading help

[Daniel Garcia Moreno <danigm src gnome org>]

commit 2c4ea6184d9b8915bf5b29cc7b7e1c2ccf3c6a7e
Author: Jeremy Bicha <jbicha ubuntu com>

    Fix loading help
    
    This should fix the Help link for Linux (& BSD).
    
    The help loading code is overly complex for Linux
    and might not help much for Windows and OS X.
    I expect Windows and OS X are still broken after
    this change but I don't have the ability to check there.
    
    Closes: https://bugzilla.gnome.org/697406
