[Python] MItKeyframe - problem changing key time

[andyland]

I have a piece of code, which should work imo, but it doesn't. so, here it is:

iter = oma.MItKeyframe( animc )
while not iter.isDone():
  val = iter.value()
  newtime = iter.time().value() + 1
  newtimeobj = om.MTime()
  newtimeobj.setValue( newtime )
  iter.setTime( newtimeobj )
  iter.next()

Unfortunately, I get an error saying:

# RuntimeError: (kInvalidParameter): value not in valid range //

I've tried setting time to several values, including iter.time(), but it always ends up with an error. Can anyone help?
