Bug 259639

Application: plasma-desktop (0.4)
KDE Platform Version: 4.5.85 (4.6 Beta2) (Compiled from sources)
Qt Version: 4.7.1
Operating System: Linux 2.6.36-ARCH i686

-- Information about the crash:
I decided to explore Plasma a little bit and discovered these different layouts. I'd never tried them so I changed to 'Newspaper Layout', and the plasma desktop crashed.

I don't know if this is related, but I've been having Xorg issues the entire day ( I upgraded Xorg ) so it might just have something to do with that.

-- Backtrace:
Application: Plasma Desktop Shell (kdeinit4), signal: Segmentation fault
