Hi, I couldn't reproduce it with emacs -Q and a freshly built version of org source code. At some point (make-string (car ev) ?\-) on line 2956 of org-table.el was being called with an argument that was a non-integer-formatted value, namely 570.0. But since I can't reproduce it at all now this is presumably an entirely transient issue!
