Google Gears upload: strange error

Question

Hi guys,

I've got this very strange error and I don't know how to deal with it. My setup is a page in which I can select one image file, (gears beta.desktop) and then it should upload. But it doesn't upload, and gives a very strange error which I can't get away. below is my code:

var filesToUpload = null;

  function progressEvent(event) {
      var bar = $("#progressBar");
      var percentage = Math.round((event.loaded / event.total) * 100);

   bar.width(percentage + '%');
  }

  function uploadState() {
   if(request.readyState == 4) {
    if(request.status != 200) {
     alert('ERROR');
    } else {
     alert('DONE');
    }
   }
  }

  function handleFiles(files) {
      if(files.length) {
       $('#loader').slideDown(500);
       var curFile = files[0];

       request.open('POST', 'upload.php');
             request.setRequestHeader("Content-Disposition", "attachment; filename=\"" + curFile.name + "\"");
          request.onreadystatechange = uploadState;
          request.upload.onprogress  = progressEvent;

          request.send(curFile.blob);
      }
  }

  init = function() {
   if(!window.google || !google.gears) {
    $('body').css('background', 'white');
    $('#gearsOn').hide();
    $('#gearsOff').show();
    return;
   }

   // verberg 'geen gears' bericht
   $('#gearsOff').hide();

   // init upload zooi (gears)
   desktop = google.gears.factory.create('beta.desktop');
   request = google.gears.factory.create('beta.httprequest');


   // on click funct
   $('#titel').click(function() {
    var newtitle = prompt("Voer een titel in voor het album.");

    if(newtitle != '' && newtitle != null) {
     $(this).text(newtitle);
    }
   });

   $('.addPictures').click(function() {
    filesToUpload = null;
    var options = { singleFile: true, filter: [ 'image/jpeg', 'image/png'] };
    desktop.openFiles(handleFiles, options);
   });
  };

  $(document).ready(init);

It gives the following error:

[Exception... "Component returned failure code: 0x80004001 (NS_ERROR_NOT_IMPLEMENTED) [nsILoadGroup.groupObserver]" nsresult: "0x80004001 (NS_ERROR_NOT_IMPLEMENTED)" location: "JS frame :: file:///Users/Fabian/Library/Application%20Support/Firefox/Profiles/oo132cjy.default/extensions/%7Be3f6c2cc-d8db-498c-af6c-499fb211db97%7D/components/componentCollectorService.js :: anonymous :: line 1155" data: no]
[Break on this error] obj = getIface(request.loadGroup.groupObserver);

Thanks in advance!!

Answer 1

I get this error when I'm using page speed - extension to firebug. If you use the same try to deactivate this extension.

Answer 2

Same here. Deactivating Page Speed fixed it...

Answer 3

disabling page speed did not helped... so uninstalled the extension.. and it works
