Hi guys! I had this problem on Mavericks today and spent 4 hours dealing with it. I have tried EVERYTHING: (1) deleting finder prefrences (2) deleting .DS_Strore files (3) cleaning desktop (4) login as a guest (5) login in safe mode (6) even reinstalling OS X (not clean install, though) nothing helped. But, eventually, I saw the post in Google groups, and it solved my problem. Solution is to obvoius. GOOGLE DRIVE WAS THE PROBLEM. Indeed, Google Drive very closely works with finder, and, as I suppouse, at some point they had conflict, which made finder relaunch all the time. So, I quit GoogleDrive and even without restarting Finder started workiking normally. P.S. I was even ready to buy external drive to make backup and make clean install. Hope, it will help you!
