Version:           2.0 beta-2 (using 4.1.2 (KDE 4.1.2), Kubuntu packages)
Compiler:          gcc
OS:                Linux (i686) release 2.6.24-21-generic

is pretty straight forward:

1. open a new document
2. open the style manager in the format menu
3. close the style manger with the close button
4. crash
