Description Mike Smith 2010-10-18 23:24:56 UTC

Version:           2.4.2 (using KDE 4.4.2) 
OS:                Linux

A konsole with a custom profile using irssi as the shell does not close correctly, causing all other konsoles running to hang.

Reproducible: Always

Steps to Reproduce:
- Create a Konsole profile using /usr/bin/irssi as the command.
- Run konsole --profile IRC and close it.
- Observe hanging.
- alt-f2 killall -9 irssi (or alt-f2 killall -9 konsole) is the only way I've found to regain the ability to use Konsoles without logging out completely.

Actual Results:  
Any currently open Konsole instances hang, and it becomes impossible to open new ones as they also hang before even displaying a window.

Expected Results:  
Less hanging.

I am currently running Ubuntu amd64, but I have also observed this bug on an Arch Linux amd64 system with KDE 4.5.1.

The same effect can be caused by closing a Konsole using the default profile after running 'exec irssi' in it; maybe this is something related to not having a shell running in it?

I can reproduce this with konsole-2.7.999.

Konsole will hangs for a while (30s ~ 1min), then it will be reponsive again. But the irrsi tab(I have opened another shell tab ) is still open and running.

The root cause is irssi responds to SIGHUP in a special way[1]: instead of dying , it performs a /RELOAD. 

So this bug is actually the same as #251566. See its comment #4 .
