Seems that if I set the color before changing to Bold/Italic/Strikethrough/Underline, the error doesn’t occur.

Christopher,

I deleted my earlier reply, since it is no longer relevant as we’ve managed to reproduce the problem. Development are investigating and we should have a fix soon. In the meantime, at least you have a workaround (and thanks for posting that), though it’s obviously not ideal.

Sorry for the inconvenience.
