This looks like bug 216215, a bug in the Oxygen style with animations enabled... Regards
unfortunately, this backtrace is missing the values of the pointers for which most of the methods are called. Is this because of missing debugging symbols (I'm no expert on backtrace) ? Other than that, yes this is the same type of crash as bug 216215 A widget gets deleted at: #30 and then ensuredPolished() is called for it later on. I made a couple of commits that might prevent that: SVN commit 1106745 by hpereiradacosta: Added protection to disable animation when target is destroyed. CCBUG: 216215 231410 M +8 -0 oxygencomboboxdata.cpp M +3 -0 oxygencomboboxdata.h M +10 -0 oxygenlabeldata.cpp M +3 -0 oxygenlabeldata.h M +18 -3 oxygenlineeditdata.cpp M +4 -5 oxygenlineeditdata.h M +8 -0 oxygenstackedwidgetdata.cpp M +3 -0 oxygenstackedwidgetdata.h WebSVN link: http://websvn.kde.org/?view=rev&revision=1106745 but am not sure whether the protection is enough. I have not yet backported it. Can anyone running on trunk double-check ? Other than that I'm still looking for a way to detect these widgets deletions.
This should be rechecked against KDE SC 4.5 (or 4.4.3 if the commit is backported...)
