Bug 256207

Application: plasma-desktop (0.3)
KDE Platform Version: 4.5.3 (KDE 4.5.3)
Qt Version: 4.7.0
Operating System: Linux 2.6.34.7-0.5-desktop x86_64
Distribution: "openSUSE 11.3 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
While attempting to duplicate bug 227157 I came across this crash.  I am using folder view.  Here are the steps I did.  I was able to duplicate this several times:

1) on desktop create a folder
2) right click on folder and move to trash
3) empty trash
4) right click on desktop
5) click "undo: trash"
6) acknowledge the error displayed

After this I see a progress bar in the notification area that doesn't go away.

7) expand the notification area so all notifications are visible
8) Press the "stop" button on the progress bar

*crash*

9) when the desktop resumes expand the notification area again
10) Press the stop button and the job is successfully canceled.

- Unusual behavior I noticed:

KDE crashes always on the first attempt at stopping the job.  The second attempt works.  As I reproduce this though, after the crash all the old jobs are back and I must stop all of them as well (I'm up to 4 now).
