python libclang parser incorrect handling of ::iterator

[d-e-e-p]

Parsing the following code with Python libclang:

#include <vector>
int main() {
  const std::vector<int> i_is_ok;
  const std::vector<int>::const_iterator i_iter_becomes_const_iterator;
  return 0;
}

incorrectly produces AST that looks like:

TRANSLATION_UNIT s: class_iter.cpp 
    FUNCTION_DECL s: main t: int () 
        COMPOUND_STMT 
            DECL_STMT 
                VAR_DECL s: i_is_ok t: const int 
            DECL_STMT 
                VAR_DECL s: const_iterator t: const int 
            RETURN_STMT 
                INTEGER_LITERAL
