Are you literally binding the clutter_actor_animate function? That's not
recommended. I think the idea is that bindings would bind the
clutter_actor_animatev function instead which does not take a variable
number of arguments. clutter_actor_animate is intended as the C
'binding' for clutter_actor_animatev which just provides a convenient
interface. Other languages are expected to bind clutter_actor_animatev
separately using whatever method makes sense. For example, the Ruby
bindings take a hash as the last argument which it then converts into
two separate arrays (one for the property names and one for the values)
to pass to clutter_actor_animatev. Calling it from Ruby then looks like
this:
some_actor.animate(Clutter::LINEAR, 1000,
"x" => 100,
"y" => 100)
Maybe if C# supports array literals or hash literals it could do
something similar.

I don't think there are any known problems with the duration. You may
want to try posting a code snippet of your binding and someone with
knowledge of C# may be able to help.
