Created attachment 64606 [details] valgrind output when digikam crashed
kipi-plugins 2.2.0 is out since few weeks. Crash still valid with this version ? Gilles Caulier
This bug is in photolayouts plugin which released first with kipi-plugins 2.2.0.
Crash is happening in kipi-plugins/photolayoutseditor/widgets/tools/ToolsDockWidget.cpp when the following is performed: w->deleteLater(); I don't know enough about Qt to know why this crash happens. -Ananta
I CC plugin author for info... Gilles Caulier
Most likely, this means that w was already deleted when you try calling deleteLater on it.
