================================================================ Dear Bug Team! Here's a 100% repeatable crash for me. With xemacs -vanilla, enter (count-screen-lines nil nil nil (minibuffer-window)) into *scratch*. Press C-j to execute this line. This instantly crashes for me. I found this when playing with git.el with my hacked display-message-or-buffer function that executes the above count-screen-lines when given a buffer.
