Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-13-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
I was just copying files from the local harddisk to an external USB drive with Dolphin. During the copy Plasma Crashed. The file copy continued normally till it finished.
I had opened other applications like Firefox 7.0.1, Skype, Konsole, Dragon Player.

Thanks for this great KDE release!
