When working in an editor I pressed Alt-Ctrl-/ which instantly crashed all
running instances of console.

From bug 232231:
-- Information about the crash:
I simultaneously hit several keys while composing a message in alpine
and the console crashed (taking all other instances along with it).
I see similar bug reports that claim reproducibility, but I can't reproduce 
the crash after some trying, and have never seen it before.

Comment 6 Dario Andres 2010-03-26 22:32:54 UTC 
Then, I wonder if the bug was introduced in 4.4branch and included by OpenSuse and Fedora, and fixed in the later versions of the packages....
Comment 7 luther 2010-04-13 14:18:20 UTC 
Confirmed in Fedora 12...  

Steps to reproduce:

Add multiple new tabs Via Ctrl-Shift-N, then copy input to all via "ctrl-shift-," Pressing Ctrl-Shift-/ once unsets copy input on the active tab... Pressing Ctrl-Shift-/ again crashes all active konsole sessions.

Comment 8 Tarun Yadav 2010-07-01 12:40:30 UTC 
Same for Linux 2.6.32-23-generic For KUBUNTU_10.04.No problem for one tab. for multiple way this is a problem indeed
Comment 9 Kurt Hindenburg 2010-07-01 17:08:34 UTC 
The fix should be  in 4.4.4 or .5 I believe.

patch.diff contain differece between SessionController.cpp code from source of konsole

I made a patch for bug 229384. I changed the use of copy_input_to_none in SessionController.cpp code in source of konsole. I have deleted the remove action for copy_in_put_to_none.
I worked well and fixes the bug.
