a.getComputedStyle(c.firstChild.firstChild, null) is null

[Webtel]

I cant describe this well becasue there is no visible problem except error in firebug..
I saw this as a bug report but in 4.0.7 version it still persists.
Can this be fixed by override (any example)? and will it be finally fixed in 4.1?

I know that it can be fixed by editing ext source but i d rather not go there everytime new version is out...

ext-all-debug.js : 6270

    {
            identity: 'RightMargin',
            fn: function(doc, div) {
                var view = doc.defaultView;
                if(view.getComputedStyle(div.firstChild.firstChild, null)==null){
                	view = doc.body.defaultView;
                }
                return !(view && view.getComputedStyle(div.firstChild.firstChild, null).marginRight != '0px');
            }

and ext-all-debug.js : 6300

        {
            identity: 'TransparentColor',
            fn: function(doc, div, view) {
                view = doc.defaultView;
                if(view.getComputedStyle(div.firstChild, null)==null){
                	view = doc.body.defaultView;
                }
                return !(view && view.getComputedStyle(div.lastChild, null).backgroundColor != 'transparent');
            }
        },

What class and method is this happening in? All classes can be overridden one method at a time easily.

[Webtel]

well, the class is as i said located around line 6270 at ext-all-debug.js (4.0.7).

What else do you need to know?

When this bug will be fixed? and again can anybody provide me an override?
