Upload Button is not visible in a MultiUploader inside a GXT Window

[GoogleCodeExporter]

What steps will reproduce the problem?
I am using the GXT library, and on a popup of the class Window 
(com.extjs.gxt.ui.client.widget.Window), I have a MultiUploader (instantiated 
by new MultiUploader(FileInputType.BUTTON)). 

The problem is that on Internet Explorer, the upload <button> is not visible 
(see screenshots). No other browser has the same problem. As you can see on the 
screenshots, I tried editing the css of the button, without success. I have 
tried both in external stylesheets and from GWT code, after the constructor of 
MultiUplader is called, but IE always ignores these rules. The strange part is 
that if I edit on IE with firebug lite the button style on the fly, and add 
width: 144px; , the problem is solved and the button appears.

What version of the product are you using? On what operating system?

I have tested it with 0.6.4 and 0.6.5-SNAPSHOT with the same results. The 
problem only appears on Windows IE9 and IE8 (I have not tested earlier 
versions). It does not appear on Safari on Windows, neither on Opera, Chrome, 
Firefox on Windows or Ubuntu.

Does the examples work in your IE browsers.

They seem to work in the virtual machines I use for testing (see my screenshot)

If they work but not your code, try to attach it here in order I could 
reproduce the issue
