0.6.3 Bug :: GIF Images / Image/Product Admin

In the admin when clicking to edit a product or the images page when you go to edit if it's a gif I get the following:

Notice: Undefined variable: source in public_html/include/image.php on line 91

Warning: imagedestroy(): supplied argument is not a valid Image resource in public_html/include/image.php on line 91

Hello, my first post.

I have deleted lines 91 and 92 from include/image.php

exactly this:

    imagedestroy($source);
    imagedestroy($destination);

And now, everytime I upload or Add or 'insert' new product, there's no advice. At least it's something.

Regards,

Sorry for my poor english.

EDIT: In fact, there's no need to delete 92 line:    imagedestroy($destination);
