I also got this issue, but it took me a while to realize it was Evernote. Awfully frustrating, and thanks for the privacy tip. I looked in Console and saw that it has something to do with displaying modified/created dates. Which may contradict the OP's use of the menubar search to reproduce, but hear me out. When I search using a Finder window, Finder crashes when I scroll to an Evernote entry. If I go into View Options, and uncheck the "Date Modified/Created" boxes from being displayed, I can run a search without a problem.
