Bug#463535: logout hangs with libgtk2.0-0 2.12.5-2

[Robin Krisher]

I was having exactly the same problem with logging out or ending session 
hanging.  Only had this problem with lenny, not etch.  After a couple days 
banging my head, finally got it to work by using my Webmin and killing the 
running process "/usr/bin/artsd -F 10 -S 4096 -b 16 -s 60 -m artsmessage -c 
drkonqi -l 3 -f"  Don't know if arts uses libgtk but if I kill the process 
first I can logout, end session or reboot without any problems.  Give it a 
shot and see if it helps you too.
