If the same option name is used in multiple config sections, e.g. by different plugins or between main settings and plugins, the option dialog highlighting code is broken. This is for example the case for the fanart.tv and theaudiodb plugins, which both have an option "use_cdart". Technically plugin options are separated into different sections, but the highlighting code ignores sections and can end up using the wrong highlighting widgets.
