Application that crashed: kword
Version of the application: 2.1.0
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-15-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
Kword chrashes if you go to the menu Settings and click on Configure Toolbars.
A bit suprising :-)

 -- Backtrace:
