variablelist titles don't appear in printed output

Hi there,

as the subject suggests: I'm writing some docbook containing 
variablelists with titles. The generated HTML looks good, but the PDF 
(generated via xsl-fo) doesn't display the title. I was trying to make 
sense out of the fo stylesheets, but without much luck. Can someone 
please confirm this behavior, and tell me what to do ? File a bug report 
perhaps ?

Thanks,
       Stefan
