Bug 282190

Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.00 (4.6.0) "release 6"
Qt Version: 4.7.1
Operating System: Linux 3.0.3-zmi x86_64
Distribution: "openSUSE 11.4 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:

The PC was idle when I got the message that plasma had crashed. I guess this could have to do with memory leaks. Usually I restart the PC every 2-3 weeks to get everything fresh. Xorg uses 2.6G virt and 1.7G res memory (according to "top"). Firefox needs 2.6G virt and 1.4G res, kontact 1G virt and 400M res, soffice.bin (LibreOffice) 3.1G virt and 170M res, konsole 700M virt and 140M res. And so on...

Maybe someone or everyone can help fixing this memory drain?
