each of these reports is plasma-desktop crashing when returning from hibernation when a QHash or QMap was freeing internal data structures. it is not always the same hash or map or the same code path in plasma, but it ends up in the same locations in Qt and we only see this crash on de-hibernation. looks like a Qt issue.
