I'm confirming this bug. The replication steps are simple from a relatively fresh and updated Natty (64 bits) install.

1) Login to a new user account, or to the "Guest" session.
2) In a terminal, issue the "top" command
3) You should notice that desktopcouch-service is eating 100% of CPU.

Workaround: It seems that login in the Ubuntu One service (from ubuntuone-control-panel-gtk) solves the 100% CPU problem.

After time, it slows my AMD quad-core to a crawl.
So I created a script: killall -9 desktopcouch-service
named the file killdesktopcouch
saved it to my home folder
made it executable with chmod a+x
then added a line to crontab
*/1 * * * * /home/user/./killdesktopcouch
and now i automatically kill the service every minute.
At least it does not continue to spawn more, eat all my ram and take up 100% of one of the cores.
Hope this is fixed soon.

Oddly enough, when I log in as Ubuntu Classic and not using Unity, desktopcouch-service does not run up 100% of my CPU but works perfectly fine.

This bug also affect one of the two users of my machine: now I have exactly 13 instances of desktop-coush running altogether one of them is eating 100% of my CPU.

I'm not sure what I did, but the issue resolved itself for me.
Logging into Ubuntu Classic, as noted, the problem didn't arise.

I too, logged into Ubuntu One and installed the Enable File Sync, Enable Contacts Sync and Bookmarks Sync as well.

I'm not sure what that installed, but upon a reboot, no more 100% CPU. Right now, 2 instance of destopcouch-service are running, both sleeping with 0% CPU.

Confirming this happening on a user account here, which is running the classic session and not using ubuntuone. For some reason the session starts couchdb, beam.smp (from erlang), and desktopcouch-service, which consumes 100% CPU and is eventually respawned until you run out of memory..

Any chance of getting this into the natty package sources?
Users will be stuck with completely unresponsive Ubuntu systems until oneiric gets out. I can confirm that it makes a bad impression on the users of my computer.
