Comment 19 for bug 50971

Just wanted to add that I can reproduce this bug with Feisty (everything up-to-date, so I guess I'm running Herd 4?).

Here's how I can reproduce it:
- Open Konsole
- #kdesu kate
- Enter password
- Immediately after Kate opened, close it (click on close-icon in upper-right corner)
- #kdesu kate

#ps aux shows some stuck processes related to this:

myuser 7984 1.7 3.0 124812 15584 pts/2 S+ 21:20 0:00 kdesu kate
root 7987 0.0 0.0 5692 376 pts/4 Ss+ 21:20 0:00 /usr/bin/kdesu_stub -
root 7990 0.0 0.2 26324 1084 pts/5 Ss+ 21:20 0:00 /usr/bin/sudo -u root /usr/bin/kdesu_stub -

Neither running "sudo -k" nor "kdesu -s" makes kdesu functional again.
