When I made the first report, I had no idea what was causing it. All  
I knew was that replacing the quadruplet with a rest made it problem  
disappear, so it looked to me as though that was the problem. You,  
with your broader knowledge of LilyPond bugs, could then help out,  
pointing out what you thought unnecessary, so  could try those  
suggestions out. Only then I thought there might be an influence from  
an earlier g, but to me that seems a strange thing. I have no idea of  
what might cause such an influence. I am gladly to help with the  
debugging of LilyPond, if you help point out what might be  
simplified. If you can isolate the problem, then please report it in  
way that expresses that best.
