[clutter] Is clipping working?

Hi,

I'm currently toying with clutter, and I tried to use
clutter_actor_set_clip in one little program.

First thing: it seems not to work :-) The program hangs while rendering.
Here's a backtrace of the hang:

Even if it worked, I'd like to get a bit more details about the function
semantics. Are the clipping coordinates relative to the actor itself? If
applied on a group, will it clip children?

Thanks,
Fred
