Changing "Actual Measure Duration" under a volta causes crash
MuseScore 2.0.1 crashes when the following is performed on the attached file:
* Delete the last 2 notes (2 16th notes under a closed volta) in the last measure.
* Right-click on the last measure. Select "Measure Properties".
* Change the "Measure Duration Actual" to "3/8".
* Click "OK" or "Apply". The application then crashes.
Note: the crash does NOT occur if the volta is removed before changing the actual measure duration.
