Comment 4 for bug 745183

Found a way to fix it manually! Open a Konsole and type [code] sudo update-alternatives --config x-www-browser [/code]

You will be presented with a list of every browser on your installation, with the current default at the top. Type in the number on this list of the browser you prefer, hit enter ... it will now be your default browser in every application.
