this has also been an issue for me. i am a heavy illustrator user and having to go back and forth between Illustrator CS5 and CS6 to get assets for Omnigraffle has been a challenge.

could someone at OMNI Group possibly respond to this thread and let us know if a fix is in the works?

thanks @peterlockhart for the drag & drop solution. it works a treat!
