Yes. :) I checked and tracker-control finalizes the manager object right 
after calling the pause function. This means the dbus proxy essentially 
disappears and the other end assumes we just terminated as an 
application. I have updated the docs and tracker-control and it works now.

    tracker-control: Don't finalize TrackerMinerManager with 
--pause-for-process

    This command line option was useless, the finalize meant we resumed
    immediately afterwards instead of waiting for the Ctrl+C for the 
main loop we
    use.

    This was noticed by Rainer M. Krug.

    libtracker-miner: Improve docs for 
tracker_miner_manager_pause_for_process()

    When finalizing the manager, it will resume the pause. The 
tracker-control
    utility was demonstrating this. Let people calling it know.

I would use that instead with 0.12.2 when it's released tomorrow.

Thanks for noticing ;)
