Using classicthesis for a CV, how can I make multi-line cvlist-labels?

I have some long labels for cvlist-items which run into the text in a very unpleasant way. How can I break the line? Simply does not do the trick.

documentclass[fontsize=10pt,paper=a4]{scrartcl}
usepackage[LabelsAligned]{currvita} % nice cv style
usepackage[ngerman]{babel}
usepackage[nochapters]{classicthesis}

begin{document}
    pagestyle{plain}
    begin{cv}{spacedallcaps{Lebenslauf}}
        %pdfbookmark[1]{Pers"onliche Daten}{PersDat}
        begin{cvlist}{spacedlowsmallcaps{Pers"onliche Daten}}label{PersDat}  % should be fixed one day
            item[This is a very long item label that should split]   And here we have som text, which does not align nicely unless the item label is split into multiple lines. For the normal itemize environnment, just putting a line break does the trick. Here it does not.
            item   born  1234
            item   some address, some city
                    other data
        end{cvlist}
    end{cv}
end{document}

Is there other CV-templates you would recommend to overcome this issue?
