Unfortunately, "Deleting the threads before the SSDP objects" seems  
to crash the backend on startup on my, dual processor, system with an  
error:

     "QThread object destroyed while thread is still running."

I attempted to debug it, but being an apparent timing fault, it works  
ok in the debugger :-(

However, regression testing seems to point fairly convincingly to  
this changeset.
