System Information
Win 10, nVidia GTX 780 Ti

Blender Version
Broken: 2.78
Worked: (unsure, but I believe it worked in 2.77)

Short description of error
When saving a PNG image using "Save As Image", Blender will always revert to RGBA even if the image was created and/or previously saved as RGB,

Exact steps for others to reproduce the error

Load default scene
Go to Image Editor and create a new image; deselect the Alpha option
Save the image
Select "Save As Image". Note that the format is now set to RGBA.

@Sergey the problem comes from BKE_imbuf_to_image_format() actually, which does weird magic to set planes based on buffer's channels, instead of using buffer's planes, see your own comment…

Am terribly tempted to just replace that by mere planes copy…
