Created attachment 74466 [details] New crash information added by DrKonqi karbon (2.5.2) on KDE Platform 4.9.2 using Qt 4.8.2 - What I was doing when the application crashed: How to reproduce: * draw two different Paths (simple path tool; fresh install) * select both layers "Shape" * group them with Ctrl+G * expand the layer "Group" and drag&drop one of the paths BETWEEN "Layer" and "Group" -> after a very short time (ca. 200ms) the program crashes (until then it seemed to work) I tested this bug on different Ubuntu variants both virtual and not virtual, it always worked.
