Short description of error
When a camera Background Image has the Depth set to Front, it's not possible to select 3d objects in normal Solid view.

Exact steps for others to reproduce the error
Please check attached blend file (has few cubes and Background Image with Depth set to Front).
It's only possible to select the cubes in X-Ray or in Wireframe view, but not in Solid View.
This seems unexpected behavior (since the image is not a 3D object), especially if the Alpha is set to 0.
