Bug#366210: konsole executes commands which are just typed at closing the window

[strawberryblack@googlemail.com]

Package:   konsole
Version:    4:3.3.2-1sarge1

You start konsole und become another user using su.
Then you type any command e.g. rm -rf /
and close the window without making any confirmation like pressing enter.
- The command will be executed.

The expected behavior is, that the command is not executed.

example:

$ cd /somewhere
$ ls
$ su
password:
# touch 1 2 3
-------------------------  closing and reopening
$ cd /somewhere
$ ls
1 2 3
$

I am using Debian GNU/Linux sarge
