Create a actual/nominal measure duration crashes Musescore

I was trying to change the actual duration of a measure. Then Musescore crashes wit the Problem Report attached.

I am using OSX 10.10.1 (Yosemite) and Musescore 1.3.

The nominal duration of the measure was 4/4 and I wanted to change the actual duration to 1/4. I pushed "Apply", then Musescore crashed. With the next trial I pressed "OK" without pressing "Apply", then the result was the same. problem_report.txt
