The new gapps is still based off 4.2.1. I changed the camera to remove Photosphere as it does not work and pershoot asked for the change to accommodate the new fix for the camera and the artifacts. I have never packaged the picasa sync together since it is a separate zip that I have not tested.
And the official CM gapps is 20121212, with a seperate package for picasa sync. If you use official gapps package, you'll get a lot of problems since it does not have non-neon support.
I will try to flash gapps-jb-picasa-20121011-signed.zip.
