I'm using fluxbox as my window manager with a custom .xsession script that starts kdeinit and dcopserver on  
login.  
  
Sometimes when attempting to start konqueror (3.4.2-0ubuntu2), konqueror blocks on a read() call.  
Here is the backtrace that occurs when I interrupt konqueror at that point in GDB:  
(gdb) bt

After killing kdeinit and all of the processes that kdeinit starts, I can start konqueror again.  
  
Here is my .xsession  
[bloom at little-cat-a ~]$ cat .xsession  
#!/bin/bash --login  
  
cleanup(){  
   kdeinit_shutdown  
   dcopserver_shutdown --wait  
   killall -9 kded  
   killall gam_server  
}  
  
trap cleanup SIGINT  
trap cleanup SIGTERM  
  
export XSESSION_PID=$$  
  
[ `hostname` == cat-in-the-hat.dnsalias.com ] && setnumlock  
kdeinit &  
xscreensaver &  
fbpanel &  
wmmemload -am -b -c &  
wmcpuload &  
[ `hostname` == little-cat-a ] && wmbattery &  
  
xkbcomp .hebrew.xkbmap $DISPLAY > /dev/null 2>&1  
#makes gnome apps work with keypad enter  
xmodmap -e 'keycode 108 = Return'  
  
rm $HOME/.xsession-errors  
  
fluxbox > $HOME/.xsession-errors 2>&1 &  
  
while true; do  
   sleep 300  
done  
  
cleanup
