Nothing to do with webkit actually. The test launches Balsa, waits for
two seconds and then takes a screenshot of the window. The bug happens
because when xdg-desktop-portal-gtk is installed Balsa takes a very
long time to start so those two seconds are not enough.

g_application_register() calls g_dbus_proxy_new_sync(), and
that times out. The problem seems to disappear if you unset
DBUS_SESSION_BUS_ADDRESS, but that's a workaround I guess :)

I haven't debugged why this happens when xdg-desktop-portal-gtk is
installed.
