Working for me on

OS X El Capitan
GNU Emacs (x86_64-apple-darwin15.3.0, NS appkit-1404.34 Version 
10.11.3 (Build 15D21)) of 2016-03-07
Org-mode version 8.3.4 (release_8.3.4-702-gcd47ab @ 

but not working anymore on

Org-mode version 8.3.4 (release_8.3.4-709-g519f78 

than I went back to

Org-mode version 8.3.4 (release_8.3.4-702-gcd47ab 

and it was not working either. But there was an update of ESS at the
same time which should have caused this.

OK - commit 9be858b of ESS is still fine.

Could you please submit this to the ESS list?
