Operating System: Linux 3.0.0-16-generic i686
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
I had just finished 'configuring Digikam' 
I  switched to import from an  Nikon L100 and the system crashed before  any images appeared. the camera was autodetected. i had an iPod connected at the time i tried to import images, the camera was turned on.
I tried recreating the crash but I recieved an 'unable to detect camera'
