It's likely a kernel bug, but you can work around it by editing 
/usr/share/pulseaudio/alsa-mixer/paths/analog-output-headphones and 
commenting out the Jack section(s).

But let me ask you - do you have working automute, i e, that the 
headphones cause the speaker to mute? If so the driver probably 
recognises the plug event somehow...
