Qt's designer core dumps

[Geert Janssens]

Hello,

A few days ago I upgraded my system with
apt-get update
apt-get upgrade

Today I want to start Qt's designer, and it core dumps. As far as I can 
remember, it worked fine just befor the upgrade.

Anybody got an idea what might be going on ?

Some extra information:
Qt was installed the default way with apt get in /usr/lib/qt-3.0.3
There are some softlinks to this directory that are used in environment 
variables:
/usr/lib/qt3 -> qt-3.0.3
/usr/lib/qt3-gcc2.95 -> qt-3.0.3

Environment variable QTDIR is set to /usr/lib/qt3
LD_LIBRARY_PATH is set to /usr/lib/qt3/lib

ldd /usr/bin/designer gives:
