Comment 2 for bug 157918

I can somewhat verify this behavior. If I add all my wallpapers (81) and scroll fast up and down the list drapes will crash. I don't get the unlaunchable behavior you get afterwards however, but I think this may be a bug with the automatic directory scanning for some reason.

How many wallpapers are in your wallpapers directory? If you clear your preferences for drapes and re-add these pictures, does it crash if you don't touch the GUI?
