Program crashes upon adding tremolo and 2/4 time signature.

Some days ago I tried to insert a 2/4 bar in the middle of a 4/4 sheet, when I did so, Musescore crashed. I tried a few times, but the program would always crash. I thought of it as a minor bug so I didn't want to bother reporting it.

However, today, after trying to add the tremolo between notes, the same thing happened. So, from my experience it's already 2 functions that make the program crash. If there are two there could be 20 for all I know since I don't use all the functions avaliable.

Thank you.
