Setting data on a tableview causes forceclose (reproduceable)

i have a window that has a tableview, and the data is populated from the local database. it works great. however, i can cause it to throw an exception (and subsequent forceclose since I'm not catching it right now until I solve this) by going back, then opening the window again, then forcing a data refresh.

To open the window, you click from the previous window. The click code is:

var superWin = Titanium.UI.createWindow({
    url: 'user/super.js',
    title: 'Super',
    fullscreen: false,
    p: win.p,
    tl: rowdata
});
superWin.close();
superWin.open();

The superWin opens and has this code:

//
// create table view (
//
Titanium.API.info('creating tableview');
tableView = Titanium.UI.createTableView({
    search: search,
    filterAttribute: 'filter',
    backgroundColor:'white'
});
 
 
 
var populateTable = function() {
    Titanium.API.info('getting supers');
  var db = Titanium.Database.open('super.db');
 
 
    var rows = db.execute(sql);
  if (rows == null || rows.rowCount == 0) {
    Titanium.API.info("tl rowcnt = 0");
        win.add(lblNone);
    }
  else {
        Titanium.API.info("t rowcnt = " + rows.rowCount);
 
        var data = [];
        var j = 0;
        Titanium.API.info("entering whileloop 99");
        var slTime = new Date();
    while (rows.isValidRow()) {
            var row = Ti.UI.createTableViewRow();
            row.height = 100;
            [code to build row]
          data.push(row);
      rows.next();
        }
        var elTime = new Date();
        Titanium.API.info('loop took: ' + (elTime - slTime));
        Titanium.API.info("done with forloop:");
        Titanium.App.fireEvent('hide_indicator');
        Ti.API.info('~287');
        Ti.API.info(data);
        Ti.API.info(data.length);
        Titanium.API.info('setting data with full array');
        tableView.setData(data);
        Titanium.API.info('search!');
        Titanium.API.info(search);
        Ti.API.info('~291');
        tableView.search = search;
        Ti.API.info('~293');
        tableView.filterAttribute = 'filter';
        win.add(tableView);
    }
}
 
 
 
populateTable();
 
 
[code to show menu option that, when clicked, will run populateTable()]

When superWin is loaded for the first time, you can click the menu button then the option to run populateTable() as many times as you want - it works each time.

If you go back [back button] then click to open the superWin, it loads as expected. But, if you click to populateTable() through the menu, populateTV() runs until it gets to tableView.setData(data), which causes: http://pastie.org/1379960

I've also tried putting the code to create the tableview within the populateTable() function. When I do this, it works for the first load, but ANYTIME I click the refresh menu button that fires populateTable(), it crashes at the same spot.
