CRASH resulting from repeat text not being exactly linked with Parts.
- add "D.C." to a measure
- File->Parts->"New All"
- in part, double click the "D.C." and change text.
- in part, unselect the "D.C.", reselect the "D.C.", and press Delete. (Observe that the changed text reverts, so you will see a regular "D.C." after the deleted)
- in main score, press undo twice.
I believe this has a similar cause to https://musescore.org/en/node/105226
I think that the solution relies in having the repeats text in parts be exactly linked to the main score repeat text, such that the main score is the one real version, while all the parts only see a linked version of that main score version.
tested on windows 8.1 x86-64 2.0.3 release.
