Error parsing @media and @page directives.

[jamesarosen]

The following won't parse:

@media all and (orientation:portrait) {
  ...
}

@media print {
  @page { margin: 0.5cm; }
}

Specifically, it yields

/myProject/vendor/less/parser.js:933
                    types = $(/^[^{]+/).trim();
                                        ^
TypeError: Cannot call method 'trim' of null
    at Object.directive (/myProject/vendor/less/parser.js:933:41)
    at $ (/myProject/vendor/less/parser.js:102:24)
    ...

[jamesarosen]

The fix is to change

types = $(/^[^{]+/).trim();

to

types = ($(/^[^{]+/) || '').trim();

(Or to change $() to return "" instead of null.)
