Viewer Crashes on "Invalid IPv6 URL"

Bug Description

A bad URL in an <a> tag in ebook can cause the Viewer to crash on viewer start.

The example I stumbled across was:

<a href="http://Tianjin–Pukou Railway Operation[/url">...</a>

(Epub example attached--also happened in azw3.)

Only happens in viewer; convert, edit book, polish all handle it fine.

The best way to fix it wasn't obvious to me, so I'm reporting it instead of trying to fix it.

These are similar bugs in the past, if it helps:
