pdf icons messed up

[wwuster]

I'm running the current version of Ubuntu with gnome. I have several pdf files on my desktop. Any .pdf file less than 1 meg shows a normal pdf icon. But any pdf file 1 MB or greater shows an orange clock (with a time of 4:00) overlaid on top of the icon.

This started happening about 1 month ago. How do you get rid of the clock emblem on pdf icons?
