I think it may be an original mistake in the spark.cpp
the kerosin::InputControl register name is "InputControl",
so change "kerosin/InputControl" to "InputControl" in Line 136.
and a similar change is needed in Line 147: "kerosin/RenderControl"
--> "RenderControl"

I am sorry, I have not test the external monitor before.
Joschka has found the solution ;-)
I think there may be a same problem in my patch:
in SceneServer::PostPhysicsUpdate() we also need:
if ( mActiveScene.get() == 0  )
{
    return;
}

And even more I try to use the monitorspark load the logfile.
but assertion failed again.
I checked the code, and found that the SparkMonitorLogFileServer is
inheritor of SimControlNode,
and all the SimControlNodes run parallelly, but the
SparkMonitorLogFileServer modifies the scene.
So it seems that we need to lock the scene.
However, I think a better solution may be let the
SparkMonitorLogFileServer inheriting from the SimulationServer.
What about your opinion?

At last, I found sometimes the server abort when the agent disconnected.
The prints said the Ruby Segmentation fault.
The Ruby is 1.8.6, I do not know if is it matter.
