I used Macjack's solution and I solved my duplicate entry problem, but now I have another problem that I didn't have before: I can't quit iTunes 11, it keeps opening itself. Is there a solution for this problem?

I am certain that this is not applicable so pardon my reply and consider it nothing but a comment.
I use a Mac Pro mid 2012. (that is VERY specific)
I have now produced more than a half dozen backups that produce a "duplicate open with" condition without use of anything but Disk Utility Repair Permissions.
The backed up disk must be COMPLETELY ejected, powered off, or physically disconnected for this to work.
Make your backup.
COMPLETELY disconnect the backup drive.
Run Repair Disk Permissions.
Ever since 10.8.4 this has worked just fine. (annoying but works)
My iTunes 11 does not launch repeatedly or fail to quit.
I can only suggest that you try running Repair Disk Permissions and see if this provides a solution.
Please realize that reparing disk permissions is only effective if followed by a Restart.
In other words.... RESTART before you draw any conclusion.
IF no difference, try setting iTunes preferences to a state that makes no network connection and Energy Saver and or Security to NOT wake for adminstrator or modem acces.

WOOPS.... forgot the OBVIOUS.
There is a new update to 10.8.5.
Perform your Software Update to apply this update and RESTART.
IF this does not solve your problem, manually download the Oct 03 10.8.5 Combo Update and manually install, then of cource, RESTART.
If that does work then perform Repair Disk Permissions and RESTART.

Thank you for your reply. Repairing disk permissions and restarting does not work. After some investigation I found that if I close I Love Stars, an app that is linked to iTunes, I can quit iTunes just fine without it auto-restarting. Another possible solution that I found while searching for an answer was to disconnect any speakers from the headphone jack.
I have already contacted the developer about the issue and I hope to be able to solve it, since I really enjoy using I Love Stars!
