Solve the following python programming problem given the following code:
def GetMissingRequires(self) : 
    "Returns the dict of missing required namespaces for the current file.

    For each non-private identifier used in the file, find either a
    goog.require, goog.provide or a created identifier that satisfies it.
    goog.require statements can satisfy the identifier by requiring either the
    namespace of the identifier or the identifier itself. goog.provide
    statements can satisfy the identifier by providing the namespace of the
    identifier. A created identifier can only satisfy the used identifier if
    it matches it exactly (necessary since things can be defined on a
    namespace in more than one file). Note that provided namespaces should be
    a subset of created namespaces, but we check both because in some cases we
    can't always detect the creation of the namespace.

    Returns:
      Returns a dictionary of key as string and value integer where each
      string(key) is a namespace that should be required by this file, but is
      not and integer(value) is first line number where it's used.
    " 
    external_dependencies = set (self._required_namespaces) 
    external_dependencies.add ('goog') 
    external_dependencies.add ('goog.module') 
    created_identifiers = set () 
    for (unused_namespace, identifier, unused_line_number) in self._created_namespaces : 
        created_identifiers.add (identifier) 
missing_requires = dict () 
    illegal_alias_statements = dict () 
    def ShouldRequireNamespace(namespace, identifier) : 
        'Checks if a namespace would normally be required.' 
        return ((not self._IsPrivateIdentifier (identifier)) and (namespace not in external_dependencies) and (namespace not in self._provided_namespaces) and (identifier not in external_dependencies) and (identifier not in created_identifiers) and (namespace not in missing_requires)) 
for ns in self._used_namespaces : 
        namespace = ns.namespace 
        identifier = ns.identifier 
        if ((not ns.alias_definition) and ShouldRequireNamespace...

    
    

    Fix the buggy line: if self._FindNamespace (ShouldRequireNamespace.identifier, self._provided_namespaces, created_identifiers, external_dependencies, missing_requires) :
