System Information
Operating System: Windows 8.1 64-bit
Graphics Card: Nvidia GeForce GT 620

Blender Version
Broken: 2.75a

Short description of error
If you set a custom property on bpy.types.RenderSettings, for example:

bpy.types.RenderSettings.custom_prop = bpy.props.IntProperty()

Then try to access it in the current scene, you'd expect the result to be 0 but instead you get (<built-in function IntProperty>, {}):

bpy.context.scene.render.custom_prop # result is (<built-in function IntProperty>, {}) instead of 0

Exact steps for others to reproduce the error
Open the attached blend file and press "Run Script". It should then raise an AssertionError.

Thnaks for the report, but no bug here, custom properties are only available for IDs (like Scene, but not RenderSettings) and a few other types like e.g. Bones. You cannot extend other types that way. I think what you want to do in this case is create a PropertyGroup gathering all your needed custom settings, and create a PropertyPointer in Scene for the group… Please see the doc for more details.

That should work perfect(maybe even better then my original idea :) Thanks for the clarification!
