-- Information about the crash:
- What I was doing when the application crashed:
I just installed latest plasma-desktop available thru FreeBSD ports. I started the KDE desktop via xinitrc & startx. 
The desktop appeared, seemingly normal. I began to customize, color scheme and fonts. I wanted to add 'konsole' to launcher menu (the Start button popup). I started typing the application name and the KDE crash handler came up.

- Unusual behavior I noticed:

- Custom settings of the application:
