When I try to open the user Documents folder from the Finder window sidebar or by navigating to it via the User path, the icons don't appear at first and the Finder window immediately closes. This is when I first open the folder after start-up. It is in Column View.
This behavior happens for several attempts and then after 4 or 5 times, settles down and works correctly. Same issues when I have the Documents folder on the dock. Same if I try to open with the shortcut (cmd-shift-O).
I have zapped the PRAM and trashed Dock and Finder preferences, but this doesn't fix the problem. It's a new machine with a clean install of SL. I had been running iAntiVirus, but removed it (using the supplied uninstaller), thinking that there was a relationship. I thought this because the behavior of the Finder window closing right away would often be accompanied with the iAntiVirus window opening. Removing the app hasn't made any difference. Thoughts?
I'm going to say that I solved my issue - hoping that I don't jinx myself. In my case, it looks like the issue was related to a corrupt or conflicting file. I had a Fetch preset file in the Documents folder. This was for an FTP site I go to frequently. I don't have Fetch on this machine, but the preset was in the Documents folder as part of a group of files I moved over from my MacBook Pro. Deleting this file has resolved the issue. I found it by the usual "divide and conquer" approach along with multiple restarts. Thereby narrowing done the problem to this one file. Crossing my fingers that was it.
