My plugin ceashes MuseScore
Now I'm coding the shakuhachi notation plugin for MuseScore v2.
I run Shakuhachi notation plugin, and "UNDO", and run the plugin again.
Then, MuseScore has clashed.
MacOSX 10.9.5 (iMac 2014 and iMac 2011)
I cannot identify the bad code.
Plese help me.
The crash does not reproduce in MacOSX 10.8.5 and Windows 7.

I tried your code on OS X Yosemite 10.10.3 and it didn't crash, even after multiple runs + undos. Must be a bug related to 10.9.5.
In reply to I tried your code on OS X by jensm
Thank you.
I updated my iMac from 10.9.5(Merverics)) to 10.10.3(Yosemite), but the situation is completely the same.
Start "Shakuhachi_Notation_test01.qml" from plugins menu or plugin creator.
Run the plugin, displayed shakuhachi notations under the notes.
Undo (command+Z), (deleted shakuhachi notations)
Re-run plugin and push "OK".
Then clash.
This phenomenon has been reproduced with a probability of 100%.
Instead of "Undo", Right click -> Select -> All Similar Elements -> DELETE has no problem.
In reply to Thank you. I updated my iMac by tcbnhrs
That's what I've done, several times. Still no crash. Have you tried clearing the plugin cache in MuseScore and reloading the plugin?
In reply to That's what I've done, by jensm
The problem has solved, but I don't understand the reason.
Line 380 was
// text = newElement(Element.STAFF_TEXT);
When I uncommented this line,
text = newElement(Element.STAFF_TEXT);
the clash has no longer happen.
Thank you.

I guess you later wrote to text, but hadn't created it due to that line being commented out
