Hi,

I am using the live-cd of Kubuntu KDE 4 remix. I face the same bug as reported in bug report 157553 with the "About Kubuntu" icon. I load from the CD, wait for the desktop to appear, hover over the icon an click the properties button. Then I click on the "Preview" tab, the window went white and Plasma restarts. This issue is reproduceable every single time.

Please find below the backtrace:
