Hello,

I am going crazy!  The attached example (a single beamer slide from a
700+ set of slides) fails on export to Beamer or even LaTeX (and
possibly any other target) with error "marker points into wrong
buffer".  The problem is caused by the evaluation of a call_ babel line.

Org is up to date with the latest emacs snapshot.  Here is the backtrace:

For some reason, emacs is trying to go to a buffer named "slide.org<2>"
when no such buffer exists.  The buffer is "slide.org"...

I will try to back up in org commits as the original file from where the
single slide came from worked last week.

Thanks,
eric
