I incorrectly assumed that there would always be at least one pointer
motion event before a pointer leave event. This is not correct; e.g. it
happens when Epiphany restores a previous browser session. Instead of
crashing when libstdc++ assertions are enabled, let's just bail. There
is probably no need to synthesize a fake motion event for WebCore.
