I just ran into what might be a simpler case of the same bug - or might be separate.

1) 4/4 score
2) add a single quarter note to any measure
3) drag 6/4 time signature to that measure

Result: measure is corrupt; only two beats.

If the following measure contains notes, they will be pulled into the measure to which the change was applied and broken up correct. but it appears we don't know how to break up a measure rest. Although it works just fine for 5/4.
