This crash does not always happen, but here are the steps to see it.
Jack, thank you. I have been able to reproduce this and will look into it for you. This is clearly a bug and I happen to know that this used to work, so it is also a regression. We will update this thread when a fix is available.
For the time being, a possible work around is to enter your line break just before the last character on the line.
Will do. Thanks, Alan!
