Setting status to resolved, no news from upstream since my last message in this 
bugreport here. If Winehq.org provides working (more recent than in Debian/
unstable) packages again feel free to re-open the bugreport.

thx && regards,

Sorry, doesn't work any longer, quoting http://www.winehq.org/site/download-deb:

"Packages here are designed to function on Ubuntu Edgy (6.10) and Dapper 
(6.06). Packages here used to also work for Debian unstable, however due to 
changes in Debian this no longer works and our Ubuntu maintainer is unable to 
support them."

Cool.  Don't forget

# WINE authentication key installation command (as root):
# wget -q http://wine.budgetdedicated.com/apt/387EE263.gpg -O- | apt-key add -

# WINE - HQ or Debian?
#
# If you are using Debian and want to make sure that apt-get
# will install the WineHQ Wine package instead of the Debian Wine
# package (which sometimes confuses APT by the same version),
# then you will need to add something like the following entry to
# /etc/apt/preferences:
#
# Package: wine
# Pin: release l=WineHQ APT Repository
# Pin-Priority: 1000
