Bug#922730: cannot browse anything

[積丹尼 Dan Jacobson]

Here's the situation on i686. Be sure to test on i686, not amd64, where
it works fine.

libwebkit2gtk-4.0-37:
  Installed: 2.23.91-1

epiphany-browser:
  Installed: 3.31.91-2

$ mkdir /tmp/p; HOME=/tmp/p epiphany-browser

You'll see it just shows it is loading about:overview, and it just loops over and over with:

** (epiphany:3475): WARNING **: 05:59:49.922: Web process crashed

(WebKitWebProcess:3679): GLib-GObject-WARNING **: 05:59:50.666: ../../../gobject/gtype.c:4265: type id '0' is invalid

(WebKitWebProcess:3679): GLib-GObject-WARNING **: 05:59:50.682: can't peek value table for type '<invalid>' which is not currently referenced

/usr/lib/i386-linux-gnu/webkit2gtk-4.0/MiniBrowser works fine though. It
can even browse web pages and files.

strace shows the loop is at

futex(0x14656c0, FUTEX_WAKE_PRIVATE, 1) = 1
clock_gettime(CLOCK_MONOTONIC, {tv_sec=5717, tv_nsec=613493764}) = 0
futex(0x143c9ec, FUTEX_WAIT_BITSET_PRIVATE|FUTEX_CLOCK_REALTIME, 0, {tv_sec=1551478070, tv_nsec=762190103}...

Anyway please fix "gtype.c:4265: type id '0' is invalid". Thank you.
