Fun :) Must be a glitch in the recent layer mode refactoring.

    Bug 778597 - Eraser paints transparent areas with BG color
    
    Add a "paint_composite_mode" field to GimpLayerModeInfo and set the
    mode of the eraser to SRC_ATOP. Defaulting to SRC_OVER for all
    painting didn't quite do it for all modes.
