Unhandled exception with small zoom

Hi

I'm using the PdfViewer for WPF control, version 15.3460.0.26. When loading a particular document and zooming out with Ctrl+ Mousewheel, at some point beyond 25% zoom, the control will crash with following call stack (also happens in your PdfViewer Getting Started demo):
