No structured view in KMail

Hi, (sorry for writing in german first. i didn't realise that this is an english list) since my kde-update (to kdebase3-3.3.1-3) with kontakt (kdepim3-3.3.1-7 ) KMail doesn't show the structural view of my messages with the folding option etc. they're simply listed like any other mails... :( i checked already the settings. and i didn't change anything on my kmail-settings since it worked last time. the folder is still defined as a mailing-list-folder and in the layout settings of kmail "structered view" is also activated.
