When I try to move a bit of System Text by unchecking the Automatic Placement box, Musescore crashes. I'm using the nightly update from July 8. July 9 came back 404. I decided to try the nightly update because my regular version that I'm using (not sure. last stable version I suppose. Properties window has no info).

Crash when editing first measure of loaded score with multi measure rests

@Bemo64: It seems you did not create this score with a stable version of MuseScore. The nightly builds are for testing purposes only. You should not use them for real work.

I think this is not at all related to the System Text items: Try to enter some music in the first measure of any of the systems in your score and you get the same crash.
It looks like this is about (loading scores that contain) multi measure rests. If you first switch them off for all parts, the crash goes away.
My investigation gives this: Editing (almost) anything in the first measure of a score, that has been loaded(!) with multi measure rests activated, crashes.

Simple way to reproduce:
1) Load 'SimpleScoreWithParts.mscz'
2) Add some music (quarter note or longer) to the first measure of either system.
-> Crash

Interestingly SimpleScoreWithParts.mscz does not crash if you enter notes shorter than a quarter (8th, 16th ...). 25_or_6_to_4_070820162015.mscz however does always crash here.
