It was mentioned on the Mint Debian 201109 thread the nightly builds could be 
installed, sources.list entires available.  Since I use Virtualbox I gave it a 
try withDebian Sueeze/

Smooth install, to early to tell much but one item that stands out,  I can know 
drag & drop/move/remove(uncheck)the column headers in kmail. Know thats the kind 
of change I can live with.  Interface looks identical, I use KDE classic.

missing package: desktop-base-trinity.
