System Information
Windows 7

Blender Version
Broken: 2.69 / current

Short description of error
FCurve.extrapolation = 'LINEAR' doesn't update the F-Curve, any graph-related operator will trigger a refresh however.
If automatic updates are too expansive, a FCurve.update() method could be used.

Exact steps for others to reproduce the error
Go to scripting view
Change 3D View to Graph editor
Paste and run this script:

import bpy

obj = bpy.context.object
obj.animation_data_create()
obj.animation_data.action = bpy.data.actions.new(name="MyAction")
fcu_z = obj.animation_data.action.fcurves.new(data_path="location", index=2)

fcu_z.extrapolation='LINEAR' # <<<<<<<<< won't refresh f-curve!
fcu_z.keyframe_points.add(2)
fcu_z.keyframe_points[0].co = 10.0, 0.0
fcu_z.keyframe_points[1].co = 20.0, 1.0

operator does update the f-curve...
bpy.context.area.type = 'GRAPH_EDITOR'
bpy.ops.graph.extrapolation_type(type='LINEAR')
bpy.context.area.type = 'TEXT_EDITOR'
