Title: KMail crashes when loosing network connection

What I was doing when the application crashed:
When I leave home in the morning, my laptop leaves range of my wireless
network, and thus KMail eventually comes up with a "could not establish
connection dialog" (as expected). However, upon closing this, it sometimes
crashes.

This is not using networkmanager or another network backend, I manage my
wireless myself.
