g_thread_init() has been unnecessary since glib 2.24 in any program that
uses GObjects. NM claims to only require glib 2.18 right now... I don't
know if that's true or not.

The right replacement is to replace

  GMutex *foo;
  ...
  foo = g_mutex_new ();
  ...
  g_mutex_lock (foo);
  ...
  g_mutex_free (foo);

with:

  GMutex foo;
  ...
  g_mutex_init (&foo);
  ...
  g_mutex_lock (&foo);
  ...
  g_mutex_clear (&foo);
