Bug 218360

Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-16-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
Crashed When Idle:

I started Audacity importing two 7-hour stereo .WMA files [using FFMpeg - 4:0.5+svn20090706-2ubuntu2 (i386)] and walked away. I came back 4-5 hours later and the screen was locked: I unlocked, and the crash handler was up. Audacity finished without perceived errors.
