Contacts Applescript dictionary broken in Mavericks?

Question

So this script works fine in Mountain Lion, but is broken in Mavericks.  Apperntly, Applescript no longer knows the class "person" anymore, even though it's still listed in the Contacts dictionary.
tell application "Contacts"
                    repeat with theName in every person
                              set theName2 to the name of theName as string
display dialog theName2
          end repeat
end tell
When I open this script under Mavericks, the person class has been replaced by  «class azf4»
When I try to replace that with "person" again and compile, I get "Expected class name but found identifier".
Running 10.9.2.  Anyone else see this?????

Answer 1

This question came up in this thread. The solution is to rebuild the launch services database. Run the following command in terminal:
/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.fram ework/Support/lsregister -kill -r -domain local -domain system -domain user
then quit and relaunch the Finder.
