%%%--- Blender version with error, and version that worked ---
Blender 2.60 to 2.69rc all fail and probably early versions as well.

- Steps for others to reproduce the error ---

In the Python console write:
override = {'selected_bases': list(bpy.context.scene.object_bases)}

[ caution, step (3) will remove all your scene objects ]
3) >>> bpy.ops.object.delete(override)

It seems to be working, but I get a lot of error prints such as:

PyContext 'window' not found
PyContext 'scene' not found
PyContext 'region' not found
PyContext 'area' not found
PyContext 'area' not found
PyContext 'screen' not found
PyContext 'screen' not found
PyContext 'active_object' not found
(...)

Those errors show in Debug and Release versions.
Reference documentation:
http://www.blender.org/documentation/blender_python_api_2_68_release/bpy.ops.html#overriding-context

Thanks%%%

%%%In a related note, I can segfault Blender very easily with this feature:

override = {'selected_bases': [bpy.context.object,]}
bpy.ops.object.delete(override)

I realize (now) that it crashes if I pass objects instead of object_bases (whatever the difference is ;).
This is pretty advanced so it's not the end of the world. It would be nice if we could not segfault though.%%%

%%%Hey Dalai, this is not a bug! You should feature those data in your fake pycontext as well!

Note best way if usually to do:
override = C.copy()
override['selected_bases'] = list(C.scene.object_bases)
bpy.ops.object.delete(override)

This just works fine…%%%

%%%I would say that at least the documentation is 'wrong', don't you agree?
