Negative on calling it busdev again, that surely has nothing to do with
a crash since it's not being used anywhere in this patch.
I still have not seen a single backtrace of what is going wrong, only
Paolo saying something about adding to main_system_bus in "the patch".
Clearly that is not in this patch! Where is that happening and why is
that so complicated for Peter C. to fix?
