Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.00 (KDE 4.3.0)
Qt Version: 4.5.2
Operating System: Linux 2.6.29.6-217.2.16.fc11.x86_64 x86_64
Distribution: "Fedora release 11 (Leonidas)"

What I was doing when the application crashed:
Middle-clicked on the calculator widget (hoping to paste in a number). A two-entry menu came up offering to open in a web browser (?). Chose this option to see what would happen, and plasma crashed.
