Earlier today I deleted some todo marks from Agenda view, also changed their deadline dates in Todo list, some of the dates were removed. There were no problems there. 

When I closed the KOrganizer window the crash occured (dealing with Todos was the only thing that was different from my usual workflow, so I guess that had something to do with the crash).
