Layout issue when upgrading

[b22c]

Hi its just install a fresh installation of 1.5.3.1 and after upgrade to 1.5.4.1 the theme header become with error. (Seescreenshot below)

On one click upgrade module before update i check the options "Upgrade theme, email and Disable non-native modules"

 

 

As you can see the search field go from the middle to the left, an error on layout.

 

After that i restore to 1.5.3.1 and the theme is correct again:

 

 

And if i upgrade again to 1.5.4.1 gives the same error on theme header

Hi i found that this happens when on SEO & Url options on backend i add a www to my url, if i remove the www, the layout become correct again. Is there an option to add the www and that theme stay correct? Is this a bug? Cheers
