libflashsupport must be in the multilib whitelist, so i386 will be in the x86_64 repo.
whitelists bad. Why isn't it getting pulled in automatically?
Not actually required by anything, opportunistically dlopened by adobe flash IIRC, doesn't fit any of our other criteria for being made multilib. It used to be part of pulseaudio-libs, but warren split it out for easier maint over time.
Fixed in 0.2.8.
