Undefined is not an object #1032

Hi everyone,

i have a pretty strange bug, when creating a Stage.

var stage = new createjs.Stage("canvas"); console.log(stage);

The constructor immediately causes this error:

[Error] TypeError: undefined is not an object (evaluating 'c.t.addEventListener') — createjs.min.js:1393

Its refers to line 1392 in create.min.js:

for (b in d)
c = d[b], c.t.addEventListener(b, c.f, !1)
