Help. ... System preferences frozen on desktop picture pane

So my System Preferences has frozen. Never done that before. It froze on the "Desktop and Screensaver" panel. I clicked on one of the iPhoto folders and it just suddenly froze. I forced quit and re-opened which didn't help. When I re-open the iPhoto folders don't load and I just get the spinning wheel. Also restarting my Mac doesn't help and relaunching the Finder doesn't help. Any ideas?

How much time have you given System Preferences to try to load the iPhoto Library? Is the iPhoto Library on your internal HDD / SSD or an external HDD?

My iPhoto library always loads instantly upon opening the Desktop/Screensaver pane. I found out I can open System Prefs while holding the shift key therefore allowing me to access all other panes. But once I click on the Desktop/Screensaver Pane it freezes in a second or two and the iPhoto folders don't show up. I just get the beach ball again.

iPhoto library is on my internal drive.

Okay so I figured it out. When I click on the iPhoto triangle therefore showing all the folders within it there's one that if I click on it it freezes preferences. This option doesn't even show up in iPhoto when I open it. Maybe it's one of those "hidden files". I there is a way to remove it that would be great.

It's a file or folder called 2012-07-20. Here's a screenshot. Maybe someone knows what it is.
