--text follows this line--

1. emacs -Q
2. C-x C-f and visit any file
3. select any region (using mouse or keyboard)
4. M-x comment-or-uncomment-region
   I get the message "combine-change-calls: buffer-undo-list broken"

Interstingly, if I select anything in scratch buffer and run
comment-or-uncomment-region everything is fine.
It seems that the bug is affecting only when I am visiting a "real" file.
