App Crashes when pressing ctrl-t or middle clicking a URL

> ### Reproduction steps
>
> * Scenario 1: middle-click a URL, such as in a YouTube video's description
>
> * Scenario 2: press `ctrl-t` from anywhere in the app
>
>
> ### Actual result
>
> In both scenarios, Grayjay freezes for about a second after the input, then crashes.
> ### Expected result
>
> * middle-clicking a URL should either open the URL in the default browser or do nothing
>
> * pressing `ctrl-t` should have done nothing since Grayjay doesn't have a tabbed interface
