Your runThread holds a reference to the CalcAddinSpread object by plain 
pointer, and the refcounted object (only to be referenced via 
com::sun::star::uno::Reference etc.) has already been destroyed when you 
still access it via that now-dangling pointer.  See salhelper/thread.hxx 
and its uses in the codebase for patterns how to use threads in LO.
