Privacy addresses generally cause me nothing but absolute misery. Despite the MAC address problem I usually end up disabling them just to be able to survive without losing my sanity due to issues like this one. I have had all kinds of applications not work reliably because of them. Including Google Chrome / Chromium etc. IRC also seems like a likely victim, but I wouldn't have noticed because I use it from a system with a static address. Perhaps a workaround would be using the MAC address override ability in the interfaces file pre-up script with "ip link set eth0 address 02:01:02:03:04:08". Randomly generate one fake MAC per boot.
