Panoramic rendering (is it broke?)

Hi,
I tried using panoramic rendering. I followed the instructions in the manual and later the ones in the noob to pro book but I don’t seem to be able to get a 360 degrees view. As a last resort I tried using the pano button of the presets but that didn’t seem to work. I thought it was supposed to make a picture by turning the camera 360 degrees or am I wrong?
I attached the blend file http://moonlit.xs4all.nl/pics/pano.blend if someone wants to have a look. I understand I could turn the camera and try to stitch the resulting pics together but doing it by pressing only the render button would be a lot easier.
Any help greatly appreciated.

Edit: Ok, figured out that the lens must be somewhere arround 5 independent of the rest (at least with my version 2.42).
