Version: (using KDE 4.3.0) OS: Linux Installed from: RedHat RPMs I noticed a strange misbehaviour of the taskbar plasmoid - there was one "window-title-slot" empty on the left - instead of moving it to the right. (Please see screenshot). At the moment I took the screenshot, plasma crashed with a segmentation fault: #6 0x09302a7c in QGraphicsLayoutItem::geometry (this=0x690084) at graphicsview/qgraphicslayoutitem.cpp:664 #7 0x09306710
