Remember to cover the basics, that is, what you expected to happen and
what in fact did happen.  You don't know how to make a good report?  See

Your bug report will be posted to the Org mailing list.
------------------------------------------------------------------------

The command `org-babel-execute-buffer' tries to execute all source code
blocks of the current buffer. When it encounters a block that is not
executable the command crashes. The attached patch makes the command ignore
non-executable blocks and move on.
