F-Curves in Graph Editor

I’m having some trouble with the cycles modifier in the graph editor.

Even with the cycles modifier added (default settings and all curves visible) the action stops outside the keyed range.

Does anyone have any ideas what could cause this to happen?

Maybe you have activated ‘Restrict Frame Range’ in the Modifier

[SOLVED]

The solution was actually simple. After filing a bug report, it was tested by the good folks at Blender. It was not a bug. The problem was that the action strip in the NLA editor has to be extended or set to ‘repeat’ otherwise the cycles modifier wouldn’t have an effect outside the keyframed range.
