While testing various error scenarios in bibtex.el that should be handled by atomic-change-group, I once got the error message cancel-change-group: Undoing to some unrelated state followed by cancel-change-group: Wrong type argument: listp, t I wanted to debug this error, but I couldn't reproduce it. I looked at the code of cancel-change-group. It's not clear to me what "Undoing to some unrelated state" means. I'd expect that atomic-change-group should not produce any errors by itself. Roland
