you miss understood, I want the back button. But no Button text. Only a back icon instead (more space). Navigationbar seem´s very buggy. Title text is alway centered, title overlapse buttons ... and I want the back button to only show an icon. ;o)
Until the next release you could alter the code within the View.js & Bar.js file.
simple find the 'defaultBackButtonText' within the 'Ext.navigation.View' class, (within the navigation folder in the Veiw.js and Bar.js)
(EDIT: Sorry: 'src/navigation/View.js' and 'src/navigatio/Bar.js')
then remove the text in both. you might then need to add a few non breaking spaces within them so the button stretches but this will remove the text.
This worked for me, then when the next release and updates are out it can be put back. hope this helps.
