#en:
VirtualBox was running, trying to start Fedora 13 Alpha; at the same time I wanted to add an element to the bottom panel (an Application Launcher widget). The minimized VirtualBox window maximized itself in a weird way and the whole desktop dissapeared

@Levick: has intentado repetir la situación para comprobar si Plasma falla nuevamente ? Gracias

(In reply to comment #1)

I can't repeat the situation because I've erased the Fedora 13 VM due of incompatibility between the Video Driver and Vbox, but I tried to recreate the situation using another VM (The WinXP one) and Plasma didn't crash this time. I can't say if there's a conection between running Linux VM's and plasma crashing, but I'm Sure that the Linux VM's have a really bad performance in Vbox against the Windows Ones... Maybe that can influence in the plasma behavior, but at the moment I don't have a Linux ISO to make the test of the situation...
