It just seams like there should be a [ ] checkbox in system services to start/stop tdedebugdialog (if not -- that may be a good feature request for the future) Before I did that, I thought I would check if anyone knew if it already existed.
I don't know if there is already a way available to do that. If not, I agree with you that it would be a good enhancement (if I ever can make it work on my computer :) ).
