Crash by entering a time signature with a last filled measure under a different time signature
In the attached score, when I attempt entering a time signature change with drag&drop or double click from the pallette in any of the leading empty bars, the application crashes in case the new bar value is shorter than current. So, it is possible to enter a 6/4 time signature, but not 3/4 or 3/8

running git-commit b2e10c7 on Archlinux.
The crash no longer appears by adding eg a 3/4 time signature (or 2/4) since d9ff5a2.
But now in this file, with the currents 3.0 dev., crash always by adding time sig (no matter the which one) -> undo
GIT commit: 051fa74 / Windows10
Steps to reproduce from scratch:
1) Create new score for flute (6 measures)
2) Add a 3/4 time signature last measure and fill it with notes (ie its complete duration)
3) Drag and drop (or double-click) a 2/4 time signature in measure 3
Result: crash
There is different scenarios depending which is the added time signature and the location: eg no crash with 3/8 added in measure 2, but crash in measure 3.
In any cases, the issue disappears by cutting the last quarter note (so, to get a last rest), or by appending a measure
Ditto in the original file (first message), ie: time_signature.mscz
. crash by adding eg a 3/4 time signature in measure 3
. no crash with the same step but after cutting the last A, last measure of second staff (oboe)
All mentioned scenarios work correct in current master:
