Custom palette crashes on creation, when "more elements" is checked
MuseScore 2.0.2 / 2.1, Mac OS X 10.11.2
Steps to reproduce the error:
1. open a(ny) (new) file
2. create a custom palette and check "More Elements" in the creation dialog box
3. Drag any element to the new custom palette
The element should be saved in the palette.
What really happens:
The program crashes.
This only happens with a newly created, empty palette and only, when "more elements" is checked.
Creating a custom palette WITHOUT "more elements" checked works perfectly fine.
Also, checking "more elements" once there are elements in the palette, will work, but according to this discussion: https://musescore.org/en/node/91716#comment-405896 it will create some chaos...
