the logic is such that unless a compiler error or some
sort of memory corruption is involved then the value
simply *cannot* be 0.

error with a static_cast:
   commands.cpp: In member function `KMacroCommand*
      CmdGen::itemsMoved(QPtrList<KEBListViewItem>*, const QString&, bool)':
   commands.cpp:514: invalid static_cast from type `KCommand*' to type ` 
      FinalAddressCommand*'
   make: *** [commands.lo] Error 1
