There might be something to investigate there. Is the asynchronous
process starting an older Org mode revision ?

​No: when I was testing with 8.2.10 (where I can still reproduce the identical problem), that was the only version I had installed (it came with Emacs 24.4).​
 
Also, you may want to put (require 'ox) somewhere in the file defined in
`org-export-async-init-file'.

​The value of that variable is nil.
