I have updated org.  Problem persists.

Attached is a full backtrace after hitting C-u C-c C-c on a table.  The
document itself has 2 headings and a small table.

I unfortunately cannot spend more time on this at the moment as I have a
presentation to make this afternoon and it's not quite ready...
