A screen capture video of the described problem

Hello Developers,

I just saw that some items in the right list on my Nautilus window appear disabled. I noticed it specifically on the "Pictures" entry. At first I thought I accidentally removed the corresponding folder.
So I moved the mouse over the entry to click it but as soon as I entered the "hitbox" it went back to normal.

So in good old debugging-fashion I randomly moved the mouse up and down.
It appears to be a graphical bug.
When I leave an entry it flickers a little. I assume it cycles through the styles "hover", "disabled" and "normal" (pure guess, I have no clue what is actually happening). So I think when I enter the field before it got back to normal it is in a weird inbetween-state.

I'll attach a little screen-grab.

Cheers
Martin
