Affects: nautilus (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
I've attached a screenshot that demonstrates this, but it's a little
difficult to see.

When clicking on the navigation buttons above the left panel, they  get
weird artifacts on them when going up and down the dir structure. The
artifacts disappear as one mouses over the buttons.

To recreate the effect in the attached image, open multiple folders as
shown in the image, and then click on the higher level one. The lower
dirs get the strange images (which disappear with a mouse over).
