--- Comment #2 from Michael Catanzaro <mcatanzaro at gnome.org> ---
OK, here's a 100% reproducer:

 * Load a website in the web view, e.g. https://webkit.org
 * Load a different website in the same web view, e.g. https://gnome.org. This triggers the creation of a new WebProcessProxy and a process swap. The new WebProcessProxy uses the same WebsiteDataStore as the original, and all works fine.
 * Ctrl+L to open the address bar dropdown, hold the down arrow key. A new WebProcessProxy is created (not sure why, is it for prewarming?) without any WebsiteDataStore.

Then WebProcessProxy::getNetworkProcessConnection() gets called from somewhere, and we crash because WebProcessProxy::setWebsiteDataStore() has not been called yet.
