it has happened several times since i've started to use this application (just a few hours ago)
dpkg -l | grep ksystem
ii ksystemlog 0.3.2-0ubuntu3 log viewin g application

this is the sigsev message that appears if i wait after the application dissapears

Este trazado inverso parece inútil.
Probablemente se deba a que sus paquetes están generados de forma que eviten la creación de trazados inversos adecuados, o la pila se ha corrompido seriamente durante el fallo de la aplicación.

This is happening to me too, in latest feisty.

I can reproduce it here every time - all I need to do is change the type of logs being viewed to anything except the kernel log, then change it back to kernel log. If I do this once it tends to happen most of the time. if I change to EVERY different type of view before coming back to the kernel log, it will ALWAYS crash while populating the kernel log view.

Note that there are two different outputs below.

I could paste more, but it seems to crash in a different place every time.
