Version:           Amarok 2 (using KDE 4.1.3)
Installed from:    Ubuntu Packages

I was playing music with Amarok in the background.  I put my camera into its cradle attached via USB and Amrok crashed as soon as the "what to do with the device" window appeared. Backtrace below:
Application: Amarok (amarok), signal SIGABRT
