Application that crashed: konqueror
Version of the application: 4.3.2 (KDE 4.3.2)
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-14-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I'm running desktop effects in ubuntu 9.10. I alt-tabbed to switch the window focus to digikam with a Nikon raw photo loaded in the window. When I then pressed ALT+F4 to close the program, I got this error message.
