Galleria issue with SAP UI5

Question

I have a dialog box that I open to run a slideshow of some photos. The first time I open the page the Galleria slideshow works fine. If I close out and reopen it that it fails and gives me: Fatal error: Could not extract a stage height from the CSS. Traced height: 0px.
Has anyone else seen this or know how to fix it? Here is my function:
CheckTire:function(oEvent){
  var oSelectedObj = oEvent.getSource().getBindingContext().getObject();
  if(oSelectedObj.ImageSource.search("TIRE") < 0)
  sap.ui.core.routing.Router.getRouter("appRouter").navTo("photoQueueView",{},true);
  else
     var oDialog = new sap.ui.commons.Dialog({title: "Tire Gallery",modal:true,showCloseButton:true});
     var galleryContent = "";
     var firstImage = oSelectedObj.ImageSource;
     var imageBase = firstImage.substring(0, firstImage.length - 6);
     for(var i = 1; i <= oSelectedObj.MaxSeqNumber; i++)
      var nextImage = "";
      if(i < 10)
      nextImage = imageBase + "0" + i + ".jpg";
      else
      nextImage = imageBase + i + ".jpg";
      galleryContent = galleryContent + "<a href='" + nextImage + "'><img src='" + nextImage + "'></a>";
     var html1 = new sap.ui.core.HTML({
      content: "<div id='galleria'> "+galleryContent+" </div>",
      preferDOM : false
     oDialog.addContent(html1);
     Galleria.run('#galleria', {
      transition: 'fade',
      transitionSpeed: 1,
      autoplay: 100
  oDialog.open();
  //sap.ui.getCore().byId('iem_header_menu').setValue(localBundle.getText('MAIN_MENU'));

Answered my own question. Had to do a "closed: function(){this.destoy();}" on the dialog box.
