Multi-bar rests

I tried to post this and lost it. I hope the other one doesn't show up.

Today I opened a score, assigned DS's and codas. All okay, everything saved.
I produced parts. All seemed okay.
I went to style, score, create multi-measure, apply. Seemed okay, score changed under the window.
Hit okay, Crash.

Multi-times.

Regards.
