Comment # 7 on bug 1084813 from Petr Cervinka

Thanks for confirmation. It means that pasystray crash was related to not
installed pulseaudio. Can't comment why it was not installed, because usually
pulseaudio is installed automatically. I will recheck dependencies for
pasystray and pulseaudio.

@Takashi, could you please check situation about crashing Firefox after
pulseaudio installation?
