Really annoying issue. Here is a quick and dirty solution that is not perfect code wise, but that is user friendly and avoids bad ratings and crashes:

if (mHelper != null) {
        try {
        mHelper.launchPurchaseFlow(this, item, RC_REQUEST, mPurchaseFinishedListener, "");
        }       
        catch(IllegalStateException ex){
            Toast.makeText(this, "Please retry in a few seconds.", Toast.LENGTH_SHORT).show();
        }
    }

This way the user just has to tap another time (2 times at worst) and gets the billing popup

Hope it helps
