--- Comment #5 from Alberto Garcia <berto at igalia.com> ---
It looks like the Yelp build still crashes, different backtrace this time:

(process:35799): Gtk-CRITICAL **: 13:40:20.270: gtk_icon_theme_get_for_screen: assertion 'GDK_IS_SCREEN (screen)' failed

** (process:35799): WARNING **: 13:40:20.271: Unable to connect to dbus: Cannot autolaunch D-Bus without X11 $DISPLAY
Unable to init server: Could not connect: Connection refused
Segmentation fault

So it seems that m_backend is null in the PlatformDisplayLibWPE destructor.
