As Dino Fancellu pointed out, its a bad bug, but I think it only applies to the asset local files in your android project.
Incredibly enough, this bug did not exist in versions 2+ (Froyo).
And my app relied heavily on passing url variables to /asset/ files.
I was only passing one variable (?id=xx), but heres how i fixed it, and tweaked it to work with multiple variables:

    // in App declare a string to hold the url parameters
    String strUrlParams;

    // In WebViewClient, Override the onReceiveError
    // Basially check if params exist in Url, strip them and save them to string
    private class HelloWebViewClient extends WebViewClient {
    @Override
    public void onReceivedError(WebView webview, int errorCode, String description, String failingUrl)
    {
        System.out.println("onReceivedError: " + description);
        if (failingUrl.contains("?")) {
                String[] temp;
                temp = failingUrl.split(Pattern.quote("?"));
                strUrlParams = temp[1]; // save params to string
                webview.loadUrl(temp[0]); // load page without params

        } else {
        webview.loadUrl("file:///android_asset/error.html");
        }
    }
    ..........
    }


    // In JavascriptInterface, add method to return the params string
    public String getUrlPString() {
    return strUrlParams;
    }


    // In the webpage that is expecting the params, add javascript to grab them.
    var getUrlParam = function(theParam) {
    var strParam = "nada";
    var query = window.location.search.substring(1);
    if(query.indexOf("=") != -1)  { // check if params
    ....
    } else { 
    // no params in url, grab params string from app
    query = app.getUrlPString();
    }
    var vars = query.split("&");
    for (var i=0;i<vars.length;i++) {
    var pair = vars[i].split("=");
    if (pair[0] == theParam) {
    strParam = pair[1];
    }
    }
    return strParam;
    }

    // example to grab the ?id=xx param 
    var theID = getUrlParam("id");

• But as per this pages question, its not a local asset file; is a http:// url. From what I understand, WebView is not throwing the error. Your php script is: "Function name must be a string in /var/www/stage/realtylog.net/iPhone/functions.php"
  This may be usefull:
  PHP Fatal error: Function name must be a string

Welcome to a horrible known bug, that Google doesn't feel like fixing, or even addressing.
