Dario, looks like the backported memleak fix introduced a regression. Looking at QGraphicsScene::~QGraphicsScene(), all items are already removed/deleted when the scene is deleted, so there is no need to use setParent(scene) on the item; it could even cause the item to be deleted twice. http://websvn.kde.org/branches/KDE/4.3/kdebase/workspace/kcontrol/randr/randrconfig.cpp?r1=986143&r2=1021730 SVN commit 1060612 by darioandres: - setParent() was not needed and could cause a crash Thanks Christoph for checking it BUG: 217935 M +0 -1 randrconfig.cpp WebSVN link: http://websvn.kde.org/?view=rev&revision=1060612 SVN commit 1060614 by darioandres: Backport of: SVN commit 1060612 by darioandres: - setParent() was not needed and could cause a crash Thanks Christoph for checking it CCBUG: 217935 M +0 -1 randrconfig.cpp WebSVN link: http://websvn.kde.org/?view=rev&revision=1060614 *** Bug 218283 has been marked as a duplicate of this bug. *** I updated my KDE installation. RPM-packet kdebase4-workspace was now created on december, 12th. There is still the same bug. I cannot open displaysettings. It seems to be the same backtrace. I looked in sources and the deleted line is not in there anymore. Could there be another error?

I can't reproduce the crash here using KDE SC 4.4 trunk with a single screen (the notebook's one) I'm using a single screen on an OpenSuSE 11.2 system with kdebase4-workspace version 4.3.4 release 8.5 from the KDE:KDE4:STABLE repository installed.
