Hi,

I'm facing a strange issue. On exporting the attached .org file to HTML, I often have to do it in 2 passes.

Most of the times the 1st pass throws an error, and the output in the *Messages* buffer is like this :

org-export-replace-src-segments-and-examples: Args out of range: 0, 0

i.e. at the end I get this error - Args out of range: 0, 0

Strangely, doing an export for the 2nd time, without deleting the output html file manages to do it successfully without throwing any errors.

Could someone examine the attached file and throw some light on what I might be doing wrong?

Thanks,
