Dashclock Widget extension not updating

I have a DashClockExtension that sometimes doesn't update.

It's using a LocalBroadcastReceiver to update the extension similar to http://bit.ly/1e4uMl0. The receiver is registered in the onInitialize() method:

@Override
    protected void onInitialize(boolean isReconnect) {
        super.onInitialize(isReconnect);

        LocalBroadcastManager broadcastMgr = LocalBroadcastManager.getInstance(this);
        if (mDashClockReceiver != null) {
            try {
                broadcastMgr.unregisterReceiver(mDashClockReceiver);
            } catch (Exception ignore) {}
        }
        mDashClockReceiver = new DashClockUpdateReceiver();
        broadcastMgr.registerReceiver(mDashClockReceiver, new IntentFilter(UPDATE_DASHCLOCK));
    }

That's how I send the broadcast:

public static void updateDashClock() {
    LocalBroadcastManager.getInstance(Application.getContext()).sendBroadcast(new Intent(UPDATE_DASHCLOCK));
}        

That's my BroadcastReceiver:

private class DashClockUpdateReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        retrieveDataAndUpdateWidget();
    }
}

I noticed that while the broadcast is triggered the receiver doesn't receive the event sometimes.
I tested it by killing my app but that doesn't reproduce the issue so I'm at a loss why this would happen.

Anyone?
