Bug Description

ubuntuone-client:
  Installed: 1.6.0-0ubuntu1

STR:
1. Start ubuntuone-control-panel-gtk, select services, disable File sync.
2. Verify that no syncdaemon is running
3. Run u1sdtool --status in the terminal (or any other SD DBus method)

Actual results:
Syncdaemon starts respawning consuming up to 50% CPU (on my machine)

Expected results:
Syncdaemon should not be consuming the CPU if it is disabled.

Now STR does not work but I was getting pretty much the same output the user @ https://bugs.launchpad.net/ubuntu/+source/ubuntuone-client/+bug/407762/comments/22 had.

STR:

1. Disable Ubuntu One File Sync service
2. Log out, log in to your session
3. Start rhythmbox with Ubuntu One music store plugin enabled.

Actual results:
ubuntuone-nautilus notices syncdaemon has acquired DBus name and starts poking it with the requests

Expeccted results:
ubuntuone-syncdaemon shuts down before acquiring the DBus name.

I had
Version: 1.6.2-0ubuntu1
and still I had to REMOVE ubuntuone-client because
1. ubuntuone-syncd was eating 117% of cpu power
2. if I unchecked its entry in the startup application lists at next start it'll be checked again
