android - null keyevent and actionid = 0 in onEditorAction() (Jelly Bean / Nexus 7)

I have an edit text which functions as a search box in my application. In Jelly Bean on my Nexus 7 when I type something into the text box which I am listening on and hit enter the KeyEvent = null and ActionId = 0 passed into the onEditorAction() method. Has anyone else encountered this? I'm thinking it might be a bug.

In the second if statement below I get a null pointer because the actionId = 0 and KeyEvent = null;

// Search field logic.
@Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
    Log.d(TAG, "onEditorAction");
    if (event != null && event.getAction() != KeyEvent.ACTION_DOWN)
        return false;
    if (actionId == EditorInfo.IME_ACTION_SEARCH
            || event.getKeyCode() == KeyEvent.KEYCODE_ENTER) {
              .....Do some stuff();
     }
}

Ended up adding in a null check for KeyEvent. Thanks to commonsware for pointing out this happens on 3.0+. Seems more like a workaround then a solution, but it works.

// Search field logic.
@Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
    Log.d(TAG, "onEditorAction");
    if (event != null && event.getAction() != KeyEvent.ACTION_DOWN) {
        return false;
    } else if (actionId == EditorInfo.IME_ACTION_SEARCH
        || event == null
        || event.getKeyCode() == KeyEvent.KEYCODE_ENTER) {
              .....Do some stuff();
    }
}
