641181 - "New Tab" button disappears when layout is changed

Status: RESOLVED INCOMPLETE

(Firefox :: Tabbed Browser, defect)

Description

[bednesti38]

User-Agent:       Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0) Gecko/20100101 Firefox/4.0
Build Identifier: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0) Gecko/20100101 Firefox/4.0

If I move anything around on the toolbar, the "create new tab" button beside your open tab will disappear. I have to keep the default layout, otherwise I cannot open new tabs.

Reproducible: Always

Steps to Reproduce:
1.Go into View/Toolbars/Customize 
2.Move any icon (ex: new window) into the area beside the tabs where you can place buttons
3.Apply your changes, and you will see that your "Open Tab" button is gone!
Actual Results:  
As I was saying, the button was gone.

Expected Results:  
The New Tab button should be there whether I keep the default layout or not. 

Default theme, Firefox RC

Does it work for you in Safe Mode or in a fresh profile? I would tend to say an extension is causing this issue.
