Not that I'm aware of, but it shouldn't be hard to do.  Thinking in Python
(untested code!):

def appendrow(model, path, iter, copy, column_numbers):
    parent_path = path[:-1]
    if parent_path:
        parent_iter = copy.get_iter(parent_path)
    else:
        parent_iter = None
    newiter = copy.append(parent_iter)
    for i in column_numbers:
        copy.set_value(newiter, i, model.get_value(iter, i))
            
    
def copymodel(model):
    column_types = []
    column_numbers = range(model.get_n_columns())
    for i in column_numbers:
        column_types.append(model.get_column_type(i))
    copy = gtk.TreeStore(*column_types)
    model.foreach(appendrow, copy, column_numbers)
    return copy
