*not* a dupe of all the "ubuntu screwed ABI" issues that end in scene.cpp:653 This one's scene.cpp:245, being 244 Window* w = stacking_order[ i ]; 245 Toplevel* topw = w->window(); So there seems a dangeling pointer in the stack @meanpt: did this happen more often or just that one time?
So far it happened only once. 2014-01-18 6:02 GMT+00:00 Jekyll Wu <adaptee@gmail.com>: > https://bugs.kde.org/show_bug.cgi?id=329989 > > Jekyll Wu <adaptee@gmail.com> changed: > > What |Removed |Added > > ---------------------------------------------------------------------------- > Version|unspecified |4.11.3 > > -- > You are receiving this mail because: > You reported the bug. >
