node.get doesn't work?

Hi,
I've just started experimenting with Services, and I can't get node.* methods to work.

If I do system.listMethods(), I get a list containing node.get, amongst others. If I then call system.methodSignature('node.get'), I get an error message "Requested method node.get signature not specified." It works for the system.* methods. I have granted permission to "load node data" to all users.

Does anyone know what is wrong? I use services ver 6.x-2.x-dev from Oct 15th (on D6.14).
