LibVLCSharp.Forms - Trouble switching pages

When switching pages using Xamarin.Forms, LibVLCSharp seems to throw a fit, specifically when navigating away from a page with the LibVLCSharp implementation. It's very easy to replicate, on my machine at least, by downloading the LibVLCSharp's samples (i.e. https://github.com/videolan/libvlcsharp) and adding a simple page change.

So to reiterate,

Xamarin.Forms (Sample seems to come with 3.0.0.446417)
Latest LibVLCSharp sample code (as of 18/09/2018 09:03 AEST or 17/09/2018 23:03 GMT)
Add a new page, and navigate to it from the page with the LibVLCSharp implementation
Run iOS example code (i.e. LibVLCSharp.Forms.Sample.iOS)

Here is a link to the forum post I have made about this, which includes the error I receive, as well as the code for the two pages I use. https://forum.videolan.org/viewtopic.php?f=32&t=146377
