[Bug 50971] Re: kdesu will not start apps

[^rooker]

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.
