Ok, I now applied the immediate watch on skeleton.Joints only and the following came up confirming your statement that this is null.
Code:
		skeleton.Joints	Das referenzierte skeleton-Objekt hat den Wert "Nothing".	Microsoft.Research.Kinect.Nui.JointsCollection
means
Code:
skeleton.Joints    The referenced skeleton-object has the value "Nothing". Microsoft.Research.Kinect.Nui.JointsCollection
Is it possible that the particular item shouldn't exist in the setting you are working with?
I think it should, but I am not completely sure about this. I found big fragments of this code here and used them for this program.

But as they are working in c sharp/ vb wpf I don't exactly know if this will work out for WinForms...


Kind regards,
