MS3 Repeatable figuring crash

The culprit was measure 23 top staff (tied Ab):

Something weird about tpc/tpc2 here (and also perhaps "event" pitch 0 ontime/len?, here clearly not my cup of tea!) :) And layout?

Via the score, the issue is solved only by selecting one Ab, and do: arrow up -> arrow down (and by re-adding a flat, start measure if wished).
The score was created with 2.1. You can reproduce the crash with this passage (select Ab -> enter Figured bass -> Escape -> Crash: or with Lyrics, Chords, Rehearsal Mark): file test.mscz

But I cannot reproduce from scratch with the current 3.x dev. and an exact copy of the file above ie: test scratch.mscz
So, considering these two points (not reproductible and former score): probably not deserves more.
See the repaired file: II. Repaired_Siciliano_(doloroso).mscz

I leave decision to developpers for close, or not, or not yet.

Doesn't crash for me with this scenario since version 3.1.
