I am running 12.04 LTS. I am having errors with nautilus. The problem says: "The problem cannot be reported: You have some obsolete package versions installed. Please upgrade the following packages and check if the problem still occurs: libatk1.0-0, libatk1.0-data"
I do not know how to go about finding these package to upgrade, and secondly, I think the problem originated when I installed Dropbox via the Ubuntu Software Center. I have uninstalled Dropbox in the hopes that it solved the problem, but it still exists.
