Okay, that is good to know. Do you know offhand (i.e., don't spend much time on this) of a simple way I can extract out the relevant matrix computation? This is not a minimal example, and it would be useful to get it down smaller. I created https://trac.sagemath.org/ticket/26389 (Simon, I have cc-ed you).
