System Information
Archlinux
Nvidia GTX 460

Blender Version
Broken: f93b76

Short description of error
When background images are enabled, they are displayed while building BVH for viewport render (instead of the normal checkered pattern).

Exact steps for others to reproduce the error

Open attached .blend: background_images_BVH.blend (warning: it has a cube with 9 subserf levels. This is so that building BVH takes long enough for the effect to be visible)
Press Shift Z to enable viewport render (the normal "loading screen" is displayed while the BVH is built)
Disable viewport render, and enable background images in the properties region
Enable viewport render again. The background image is displayed while building the BVH.

Doesn't seem a serious bug to me. The viewport is simply cleared to the default background when render starts, which includes the background image. No harm done afaict, it might even be useful.

I agree it's pretty minor :)

It just struck me as odd, especially when the view is in perspective and/or not aligned to an axis (so background image is not normally visible), yet when switching to viewport render mode it appears for a second.
