Not just that, but Unstable is also transitioning to a new gcc and g++ 
version, resulting in an incompatable ABI change for C++ libraries. 
They're also moving to GNOME 2 and KDE3, and changing a bunch of other 
big stuff. Expect breakage.

I've even had problems with sarge when apt or dpkg corrupt the status 
file. This never happened with woody when I was tracking that before 
release.

Back up /var/lib/dpkg before you try anything from sarge or sid.
