Hi Josiah,

Yes, I downloaded the same file and tried again and got the following debug trace:

Debugger entered--Lisp error: (error "PDF file ./presentation-1.pdf wasn't produced: Runaway argument")
  signal(error ("PDF file ./presentation-1.pdf wasn't produced: Runaway argument"))
  error("PDF file ./presentation-1.pdf wasn't produced: Runaway argument")
  org-latex-compile("./presentation-1.tex")
  #[(file) "\301!\207" [file org-latex-compile] 2]("./presentation-1.tex")
  org-export-to-file(beamer "./presentation-1.tex" nil nil nil nil nil #[(file) "\301!\207" [file org-latex-compile] 2])
  org-beamer-export-to-pdf(nil nil nil nil)
  (org-open-file (org-beamer-export-to-pdf nil s v b))
  (if a (org-beamer-export-to-pdf t s v b) (org-open-file (org-beamer-export-to-pdf nil s v b)))
  (lambda (a s v b) (if a (org-beamer-export-to-pdf t s v b) (org-open-file (org-beamer-export-to-pdf nil s v b))))(nil nil nil nil)
  org-export-dispatch(nil)
  call-interactively(org-export-dispatch nil nil)

I have attached the screen snapshot and conversion log  as well. I'm running on CentOS 6.5 box. 

Thanks for looking into it! Much obliged.

Best,
Suhas

Hi Suhas,

> Upon closer examination, I found that there are two commands to export to PDF.
> C-c C-e l small-o (converts to "regular" pdf)
> C-c C-e l capital-O (converts to "presentation" pdf, i.e., converts all headings to slides)

Yes, I exported via the Beamer exporter with C-c C-e l O.  

> I tested "C-c C-e l O" successfully for a simple text but I'm getting the following error for the attached file in my last email.

I just tried this with 8.2.5h and could not reproduce your problem.
Are you sure you're exporting the exact same file you attached?


Best,

Josiah
