Full trace of all threads of plasmawindowed crash in QObject::parent
plasmawindowed org.kde.plasma.kickoff crashed when closing with a different
trace in QObject::parent. The crash might've been a null pointer dereference
since QObject::parent had this=0x0.
Core was generated by `plasmawindowed org.kde.plasma.kickoff'.
Program terminated with signal SIGSEGV, Segmentation fault.
