Can't open files after upgrading to Mavericks
Maybe you could start by moving ~/Library/Preferences/com.apple.finder.plist (where ~ is you're home folder) to the desktop and restart the Finder by typing sudo killall Finder into terminal. If it works with another user, it may be something in you're Library folder that is causing the problem. I would also check you're startup items under System Preferences:Users:Login Items. Another thing that could help is check you're logs in the Console Application and see if it is reporting anything unusual there.
