After r113849: <http://trac.webkit.org/changeset/113849>, having pulseaudio-utils was made an implicit requirement for running the tests. Although Phillipe fixed it partially in r113850: <http://trac.webkit.org/changeset/113850>, it still crashes when pulseaudio-utils is installed but pactl doesn't provide an index for pulseaudio loaded modules.
