Memory leak when using Gio::File

[Галымжан <kozhayev gmail com>]

I have giomm 2.30.0 and glibmm 2.30.0. Test program:

#include <iostream>

#include <glibmm.h>

#include <giomm.h>

int main(int argc, char const *argv[]) {

  g_type_init();

  Glib::RefPtr<Gio::File> file = Gio::File::create_for_path("test.txt");

  if (file->query_exists()) {

    std::cout << "File is there" << std::endl;

  }

  return 0;

}

Compilation and running:

> g++ giomm-test.cpp -o giomm-test `pkg-config --libs --cflags giomm-2.4`

> valgrind --leak-check=full --show-possibly-lost=no giomm-test

Why is there a memory leak? If I don't use Gio::File there is no memory leak.
