Unity daemons from anothe users appear in my session

Hi all, I have a problem in Ubuntu 12.10, in my session I see processes of another users running.

I created a new user for testing some stuff, but now I can see that if I work in that user session, and then I logout and log into my session wich is another user session I see some processes of that user running in my session, this processes are:

unity-files-daemon
unity-music-daemon
unity-applications-daemon

I do not have idea what is happening here, because if I close that session all those processes should be killed because they were started by that user.

I attach a picture where you can see that my current user is "jako" but there are some Unity prcesses started by the user "humanos". I prevously closed humanos's session.

I also note that I have some repeated Unity processes in my session, those three processes are also repeated in my session.

Sorry about my English, I speak Spanish
