Removing empty entries with webpack

For example, I've got the following entry:

webpackJsonp([0,3],[
/* 0 */
/***/ function(module, exports, __webpack_require__) {

    'use strict';

    __webpack_require__(1);

    __webpack_require__(6);

/***/ },
/* 1 */
/***/ function(module, exports, __webpack_require__) {

    'use strict';

    __webpack_require__(2);

/***/ },
/* 2 */
/***/ function(module, exports) {

    // removed by extract-text-webpack-plugin

/***/ },
/* 3 */,
/* 4 */,
/* 5 */,
/* 6 */
/***/ function(module, exports) {

    "use strict";

/***/ }
]);

As you can see this entry is doing nothing. Is it possible to tell webpack to remove this entry (because it's empty)?
