Comment 14 for bug 254943

i created a test script run this from your konsole
#!/bin/bash
kill -HUP $PPID

ok first thing firs SIGHUP is a signal that modems used to send(when looing connecion)
many applications do this also for the same purpose(sshd,screen, screenwrappers)
if the shell receives SIGHUP it will exit(nothing crashes afaik)(it will return 129 (128 + 1(hup) ,maybe this is what make konsole notify me)

for some reason konsole sees this as a crash of bash

as a final note:
this is just gesswork experianced when wrapping screen (i must trap and forward sighup to kill the last shell(yes i have to manny)
i have never looked in the code of konsole or bash
