angular: Alpha35: Empty event expression produce cryptic error

Related: #3664 (should be fixed together)

I have a template with the following element:

<input type="file" id="picture" accept="image/*"
                           (change)="onFileSelected(f, $event)"
                           (fileread)>

On alpha 33 it worked great. On alpha35 it produces the following runtime error:

EXCEPTION: TypeError: Cannot set property 'lastInBinding' of undefined
angular2.js:13030 STACKTRACE:

The following modification still produces the error:

<input type="file" id="picture" accept="image/*"
                           (change)="onFileSelected(f, $event)"
                           (fileread)="">

This one works

<input type="file" id="picture" accept="image/*"
                           (change)="onFileSelected(f, $event)"
                           (fileread)="x">

This error is still occuring in RC1 when using something like <a (click)></a>).

(Forgot to add handler to an anchor element and Chrome spit this out)
