Yes, the problem is that it's not documented in the gtk+ doc. But C gtk+ 
apps do this and looking at the gtk+ source code there is something like:

GdkRectangle window_rect;

if (!rect)
{
  window_rect.x = ...
  ...

  rect = &window_rect;
}

So it's explicitly coded and allowed input for this function.

Should I report it in bugzilla?
