Hi All,
Help Plz !!,Am a KDE noob trying to get a small tutorial app written by Larossa
working, so far been pulling my hair out... Can anyone let me know what I am
doing wrong ?

My system Details :

Kde libs - 3.4.2
kernel - 2.6.9-1.667smp
Distro - FC3


I have 3 files (see text below)
main.cpp
p3.cpp
p3.h

I compile them as follows
	$g++ -c -I/usr/include/kde -I/usr/lib/qt-3.3/include -fno-rtti main.cpp
	moc p3.h -o p3.moc
	$g++ -c -I/usr/include/kde -I/usr/lib/qt-3.3/include -fno-rtti p3.cpp
	$g++ -L/usr/include/kde -L/usr/lib/qt-3.3/lib -lkdeui -lkdecore -lqt-mt -ldl -o
p3 main.o p3.o

The binary gets generated but crashes everytime it opens , i can see the window
pop up but then immediately crashes , following is the text from the backtrace
log
