"Add/Remove Line Breaks" causes crash Ver. 2.0.1Rev. b25f81d

"Add/Remove Line Breaks" causes MuseScore program to crash. This did not happen for the score when I set the break to every four measures. However, after creating a parts, I tried to add lines every 4 measures It worked fine for the part from the second staff. However, the same operation on the part from the first staff caused the program to crash. This happen repeatedly following the exact sequence. Multimeasure rests were used.

The only difference I can see is that the first part had an odd number (7) of multimeasure rests and my selection was to break at an even number (4) of measures. This was not true of the second part which had even number (8) multimeasure rests. Also, I had not yet saved the parts when making the changes. (which the new version makes very easy. Thank you!)

Most of the above probably doesn't matter, but I thought it might be helpful.
