I’m attaching an archive containing armhf debian packages for webbrowser-app built from the branch I mentioned in the previous comment. To reproduce the issue, install those packages onto a RW device, then launch the browser app, open a new window from the drawer menu next to the address bar, then open the app spread and swipe away one of the browser windows to close it. That reliably triggers the crash for me.
