I repeated this test that prompted this extra code with this code removed and it
still worked.  We call setlocale() early on in startup.

-  // setlocale() by pulling out the conversion between FilePath and
-  // WebCore String out of the renderer and using string16 in place of
-  // FilePath for IPC.
-  const char* locale = setlocale(LC_ALL, "");
-  LOG_IF(WARNING, locale == NULL) << "setlocale failed.";

   scoped_ptr<icu::TimeZone> zone(icu::TimeZone::createDefault());
 
   FilePath module_path;
   if (PathService::Get(base::DIR_MODULE, &module_path))
     media::InitializeMediaLibrary(module_path);
