PhotoChooserTask cant crop big photo

Question

When I want to pick photo from my library, and initially do something with this photo I want to crop it and resize to 300x300. Everything is OK, until I choose a big photo.

When I pick a big image (10000x6000) PhotoChooserTask does nothing (from the user's point of view), PhotoChooserTask just crashes (not the application). Then when I try picking another one I get "Not allowed to call Show() multiple times before an invocation returns" exception.

It seems PhotoChooserTask still has the previous object inside, and I don't know how to dispose or clear PhotoChooserTask.

PS. without setting

chooser.PixelHeight = 300;
chooser.PixelWidth = 300;

Photo will set, and everything is ok.

PS2.

Samsung ATIV S does not have a problem. Only nokia 1320 ,520 and 530

PhotoChooserTask chooser = new PhotoChooserTask();

try
{
    chooser.ShowCamera = true;
    chooser.PixelHeight = 300;
    chooser.PixelWidth = 300;

    chooser.Completed += (s, result) =>
    {
        if (result.Error != null){ return; }
        if (result.ChosenPhoto != null)
        {
           var bitmap = new BitmapImage();
           bitmap.SetSource(result.ChosenPhoto);
           Service.uploadPhoto(receiver, (ImageSource)bitmap);
        }
    };
    chooser.Show();
 }
 catch (Exception ex)
 {
     MessageBox.Show(ex.Message);
 }

When the photo is big and height is set the debugger doesn't enters inside chooser.Completed

The image size is probably the problem.

An image of 10000x6000 will take approximately 240MB in memory itself (10000 * 6000 * 4 bytes per pixel). That ammount of memory is probably causing the app using the PhotoChooserTask to crash and not to return anything to your app.
