Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.2.85 (KDE 4.2.85 (KDE 4.3 Beta1))
Qt Version: 4.5.1
Operating System: Linux 2.6.28-gentoo-r5 x86_64

What I was doing when the application crashed:
Shortly after logging in, plasma will crash as I'm trying to load all my apps that I keep running.  This wasn't a problem before going to kde 4.2.85, and hasn't been a problem since probably the 4.2 snapshots.
