I've just started up a minimal Emacs instance and loaded the babel
portion of your attached config, but I am able to export your attached
org file w/o error. A couple of questions.
1) are you able to export to latex? If so, then maybe the issue has to
do with fontification of R code by htmlize-buffer
Yes - export to latex (and from there to pdf) are working.
2) could you send in the actual error being reported by Emacs, or a
stack trace?
These are the messages in emacs:
Select command: Exporting...
org-babel-exp processing...Fontifying *temp*... (regexps.............)
org-babel-exp processing...font-lock-fontify-keywords-region: Invalid regexp: "Regular _expression_ too big"
How can I get a stack trace?
One more thing: if I start emacs with the -Q option, it works. So I assume it is something in my
emacs.org file. What is the easiest way to avoid that source blocks under a heading in the
emacs.org file are executed?

Yes, this is for Sweave like behavior.
If you have a session specified for every block in the buffer, and you
are exporting the buffer, there are cases when you need a block to be
executed (e.g. because it sets the value of a variable used by a
subsequent block) even though you *do not* want the results of the block
included in the final document. To support these use cases, on export
every block with a session is executed so that it's effects on the
persist session takes place.
OK - that makes sense.
If you need any further info, please let me know.
Thanks,
Rainer
