So the digging has been done and the results are almost there. I have a new (broken) patch set up that shows the state of things. The problem is a circular dependency: in Tuplet_bracket::calc_position_and_height, there is a variable my_offset that tries to look up the Y-offset of the grob. This triggers positioning-done in the Y-parent, which already needs to know the positions that will eventually be furnished by calc_position_and_height. If anyone sees an obvious workaround, let me know! I'll let it simmer for a couple days and see if I can come up with something as well. Cheers, MS
