4.3.1, Mavericks, Aperture, and Quicklook not working

Hi,
Macbook Pro running Mavericks with FM 4.3.1 installed.
Trying to access jpeg files stored by Aperture through the photo browser.
When I Command-Y to Quicklook I get a message as attached.
If I open the double-click image to open it with Preview first, it then works properly with Quicklook.
Help!
Thanks
