I can confirm this is happening to me as well. It just started a few days ago after an update. When I log in, Chromium starts and opens two blank tabs w/o my permission.

Also, an instance of the browser appears in the middle of the screen. When this happens, I get an inconsistent browsing experince in Chromium, where it is randomly unable to connect to web sites or download components referenced by web pages (e.g., CSS files, JS files, etc.). I can fix by closing the browser and also both the background sessions, then restarting Chromium. I have never configured Chromium to start up when I log into my session. This has happened without my explicit permission or consent. If I go to Session and Startup's Application Autostart tab, Chromium appears in the list and is checked. I did not configure this. Expected behavior: No part of Chromium opens at all, not even a background process, until I launch the browser for the first time. I am using a copy of Xubuntu 13.04 that was upgraded from Xubuntu 12.10. This problem was happening for several weeks back with Xubuntu 12.10, too.
