The problem is the compiler, as the packages of QT are from woody, they
are compiled with gcc-2.95. While you are using gcc-3.3 to compile your
app. Unfortunately, the Application Binary Interface of c++ Code changed
from 2.95 to 3.0 to 3.1 to 3.2, so either get QT-Libs from sarge (they
are 3.1.1) if you don't need KDE (woody KDE-Libs won't work with these
QT Libs - or get KDE from unstable). Anyway you can also use the Libs
you have, export CC=gcc-2.95 and CXX=gcc-2.95 before running configure,
that should work.
