Changing note value after dragging time signature causes corruption and a crash in linked staves
Nightly, October 16 (889dc16) / Windows 7
1. Create a score for flûte, 4/4, 32 measures
2. Before all other action, change 4 /4 to 6/8 (for example), by dragging this last TimeSig from the palette.
3. Now, change the value note (default quarter note) by selecting the eighth note value
Result : corruption
And after activation of the Note entry mode.
Additionnal note : this issue does not occurs if initially you select the TimeSig (4/4) followed by double-click on 6/8 in the palette.

I unfortunately could not locate the occurrence of this issue. I can always reproduce it on several Nigthlies, as the latest that I can use, May 19.
EDIT: You will also notice that this issue "only" occurs in the first two measures.
Reproduced. Just for clarity:
1. Create 4/4 score.
2. Apply 6/8 to first bar.
3. Select eighth (changing the values of the rests in the first bar).
Result: Corruption.
Notes:
This is only visible if you don't subsequently enter notes.
Corruption is also reproducible if notes are present prior to performing steps 2-3.
Using MuseScore 2.0 Nightly Build 0f25585 - Mac 10.7.5.
I am not at all agree with the title change for two reasons:
1) As mentioned in my first post in additional note, this issue only occurs when there is action of dragging the new time signature. It does not happen if you select 4/4, and then doing a double-click on the 6/8 TimeSig. So, this aspect of dragging is fondamental, and you have removed it in the title.
2) I can not reproduce when you say " Corruption is also reproducible if notes are present prior to performing steps 2-3."
Maybe I missed something, but if the here notes are present, it means that you are (or have been) in Note entry mode, and in this case, corruption is absent.
1. Okay - better title?
2. Create a 4/4 score, enter notes in the first bar, and perform steps 2-3 - can you reproduce? What you maybe refer to is entering notes after performing such steps, in which case corruption is indeed absent.
I can not reproduce because there are two necessary conditions for this issue: drag and drop the new TimeSig, and do not enable the Note Entry mode previously.
It would be useful to demonstrate the corruption you describe with screenshots step by step. Thanks.
Here is a screencast .
Thanks for the screencast.

This has the effect of moving the corruption in the second measure. So, we can leave the title as well now.

1. Open "My First Score "
![test1.jpg]( "test1.jpg")
2. "I" -> select staff1 -> Add linked staff (Bass clef) -> Ok
3. Fill the first measure with four quarter notes
4. Exit note entry mode
5. Drag and drop the 6/8 TimeSig
6. Always in inactive note entry mode, select the eighth note value
Result: crash
Additionnal note: you notice that changing time signature causes an octave jump in the first staff. I fill soon a new issue for that.
