System Information
Ubuntu 14.04.2 LTS 64-bit
AMD A8-5550M APU with Radeon(tm) HD Graphics × 4
AMD Radeon HD 8550G
Blender Version
Broken: 'Blender V2.55.1 and newer' as the OpenEXR file states; yet it can be any version.
Short description of error
Case scenario: Rendering an image of X and Y size (here being 1920 x 1080 in example image).
Rendering a scene (with or without all passes enabled) yields expected results for the "dataWindow" and "displayWindow" variables.
Both are set to -> (0, 0) - (1919, 1079).
'dataWindow': (0, 0) - (1919, 1079), 'displayWindow': (0, 0) - (1919, 1079),
Rendering a scene with [ bpy.context.scene.render.use_border = True ] and setting the render border should yield two different results. The Variable "displayWindow" should stay exactly the same as it represents the render size of 1920 x 1080 and "dataWindow" should represent the render border region.
'dataWindow': (0, 0) - (959, 539), 'displayWindow': (0, 0) - (1919, 1079), }

}Exact steps for others to reproduce the error
1 - Setup a render border inside camera,
2 - Select OpenEXR or OpenEXR-Multilayer image formats,
3 - Render,
4 - Save render as a file.
Optional steps:
5 - Install python2 or 3 OpenEXR bindings,
6 - Dump the file header using code below:
import OpenEXR as exr
file = exr.InputFile("filename")
print(file.header())Suplied .blend:
