Application no longer allowed access to the desktop in Mavericks

Question

HI I have a particularly irritating problem.  For a while now any application that attempts to access the desktop upon initial startup or to save a file to it will hang requiring a force quit from the finder.  Installations go without a hitch.  This problem only appears when apps either default to the desktop on first run or when they are directed to save a file from them to the desktop.  Drag and drop operations from local folders like documents and downloads or external drives or folders to the desktop have to problem doing so.  I have run repair permissions on my main drive.
Partial System log showing current app problem.

Any Ideas on what to do so I can get functionality back on my system.  Currently I am on a late 2007 iMac extreme edition 2.88gighertz model with 4 gigs of ram.  I am running the latest updates to Mavericks.  Overall its not a problem with programs that I can set or open with no preference to start but there are some programs that default to the desktop upon initial startup.  These are effectively unusable at present.  Thanks in advance for the help.

Repairing disk permissions with Disk Utility only apply to system and apps that are installed using an installer.  To repair/reset Home folder permissions see this post by Linc Davis:

Triple-click anywhere in the following line on this page to select it:
{ sudo chflags -R nouchg,nouappnd ~ $TMPDIR..; sudo chown -R $UID:staff ~ $_; sudo chmod -R u+rwX ~ $_; chmod -R -N ~ $_; } 2>&-
Copy the selected text to the Clipboard by pressing the key combination command-C.
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window by pressing command-V. I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting.
You'll be prompted for your login password. Nothing will be displayed when you type it. You may get a one-time warning to be careful. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The command may take a few minutes to run, or perhaps longer if you have literally millions of files in your home folder. Wait for a new line ending in a dollar sign ($) to appear, then quit Terminal.
Or you can do it from the Recovery volume as described by machack in this post:

1. Restart holding down the Command and R keys.
2. You’ll be at the Repair Utilities screen. Click the Utilities item in the Menu Bar, then click Terminal.
3. In the Terminal window, type resetpassword and hit Return.
4. The password reset utility window launches, but you’re not going to reset the password. Instead, click on icon for your Mac’s hard drive at the top. From the dropdown below it, select the user account where you’re having issues.
5. At the bottom of the window, you’ll see an area labeled Reset Home Directory Permissions and ACLs. Click the Reset button there.
The process takes a few minutes. When it’s completed, restart.
