 Okay, I stepped with print_r() through the menu-code and detected that 
getPageOverlay() didn't
got executed at all (there is the nice line: // Unset vital fields that 
are NOT allowed to be overlaid:
which told me I was right).
 I search on the typo-folder for extensions overwriting the function, 
and I found:

 altern_lang_menu_page_title
 altern_lang_page_link

 which both overwrite getPageOverlay with a erronous version.
 If their functionality is integrated into 4.0+, why aren't they marked 
obsolete? Or at least their
life-time (compatibility) is reduced to <4.0?

 The funny thing is, searching the topic in relation to the 
extension-names gives a hint:

http://www.typo3.net/forum/list/list_post//37043/?page=1#pid138804

 It's not the exactly same issue, but is caused by the same underlying 
problem. Shouldn't this
be made known?
