This shows a problem evaluating a babel #+call or an inline source block
somewhere between positions 1 and 3532 in the buffer. I suspect those
call_skype thingies in your text are misinterpreted as babel calls
somehow.

The thing is that org-babel-exp-non-block-elements does not exist any
longer: it was taken out last December (from both master and maint).
With recent org, I don't have a problem exporting your text, so my
suggestion is: upgrade.
