When the web process crashes, the web view goes white and never recovers. We used to signal the UI process to display an error page. Recently this worked for everything except AC, then it was fixed for AC as well, and now it's seems to be broken either always or almost always.
OK, the signal is still being sent, because Epiphany is loading its error page in the web view. If I click View Source on the empty page, the source for the error page is displayed properly. But WebKit never renders the page: it just leaves the page as entirely white (or sometimes entirely black).
