A strange thing I've discovered: the crash does only occur when stopping + re-starting plasma-desktop from a currently running KDE session, but not when starting a new KDE session.

I made a plasmoid. BZFriendsPlasmoid, you can find it here: http://bzfriendsplasm.svn.sourceforge.net/viewvc/bzfriendsplasm/ I dont know why, but plasma desktop always craches on startup if my plasmoid is on the workplace...but generally my plasmoid works fine.. I hope that's not my fault...I cannot track back to my plasmoid...However if you have an idea("workaround") how to avoid this bug, with changing my plasmoid's source please contact with me: zuiadaton@gmail.com I tried my plasmoid on other distribution (Kubuntu KDE4.6) there is nothing bad behavior Akos(zuii) -- Backtrace (Reduced): #7 0xb6a48907 in QGraphicsLayoutItem::isLayout (this=0x85d8b60) at graphicsview/qgraphicslayoutitem.cpp:868 #8 0xb6a47542 in QGraphicsLayoutPrivate::activateRecursive (this=0x85dafb8, item=0x85d8b60) at graphicsview/qgraphicslayout_p.cpp:181 #9 0xb6a4757d in QGraphicsLayoutPrivate::activateRecursive (this=0x85dafb8, item=0x85c1818) at graphicsview/qgraphicslayout_p.cpp:189 #10 0xb6a47006 in QGraphicsLayout::activate (this=0x85c1818) at graphicsview/qgraphicslayout.cpp:261 #11 0xb6a470e4 in QGraphicsLayout::widgetEvent (this=0x85c1818, e=0x8874488) at graphicsview/qgraphicslayout.cpp:372
