Reviewing Unity r2956 at unityshell.cpp:1435 I find:
QuicklistManager* qm = QuicklistManager::Default();
if (qm)
{
QuicklistView* view = qm->Current();
if (view)
{
nux::Geometry const& geo = view->GetAbsoluteGeometry(); <============
CompRegion quicklist_region(geo.x, geo.y, geo.width, geo.height);
if (damage.intersects(quicklist_region))
view->QueueDraw();
}
}
Looks like view is a stale pointer (and not null either).
