nautilus segfault (frequent background changes?)

[ssducf]

Nautilus crashes once every couple of days with a segfault.
I'm running variety (automatic background changer), I wonder if perhaps there is a race condition between variety updating the image and nautilus trying to read it.

Here's the tail end of the latest crash. I may have enother in a day or so with more debugging symbols enabled.

Do you still see that problem in newer versions?
