Solve the following python programming problem given the following code:
def mutual_accessibility(graph) : 
    '
    Mutual-accessibility matrix (strongly connected components).

    @type  graph: graph, digraph
    @param graph: Graph.

    @rtype:  dictionary
    @return: Mutual-accessibility information for each node.
    ' 
    recursionlimit = getrecursionlimit () 
    setrecursionlimit (max ((len (graph.nodes ()) * 2), stack)) 
    mutual_access = { 
        
} 
    stack = [] 
    low = { 
        
} 
    def visit(node) : 
        if (node in low) : 
            return 
num = len (low) 
        low [node] = num 
        stack_pos = len (stack) 
        stack.append (node) 
        for successor in graph.neighbors (node) : 
            visit (successor) 
            low [node] = min (low [node], low [successor]) 
if (num == low [node]) : 
            component = stack [stack_pos :] 
            del stack [stack_pos :] 
            component.sort () 
            for each in component : 
                mutual_access [each] = component 
for item in component : 
                low [item] = len (graph) 
for node in graph : 
        visit (node) 
setrecursionlimit (recursionlimit) 
    return mutual_access 

    
    

    Fix the buggy line: setrecursionlimit (max ((len (graph.nodes ()) * 2), stack))
