Bug 162438

Version:            (using Devel)
Installed from:    Compiled sources
Compiler:          gcc (GCC) 4.2.3 (Ubuntu 4.2.3-2ubuntu7) 
OS:                Linux

I've tried to add an activity (through the "menu" in the upper right corner). It worked. I've added some widgets, changed background.. no problem at all. Than I've added another plasmoid and here it happend. It worked first, but when I switched back everytime I clicked the desktop of the first containment plasma crashed. (hope I've recalled everything right).

I've compiled KDE trunk from source on Ubuntu 8.04, I've got an ATI mobility graphics card running the fglrx driver (don't know if important.. but don't think so in this case). I've desktop effects enabled (opengl).

Backtrace:
Application: Plasma Workspace (<unknown>), signal SIGSEGV
