I moved both files to my Desktop. I rebooted and the problem remains. I also logged in as another user and did not have the problem opening a .png. So, it is definitely something with my user.
I did look with dpkg -S to try to determine where the files came from. They were not a part of any package. I imagine they must come from some change made to the nautilus preferences. I do have kde installed as well and have never used kde with the other user that is not having this problem. Thanks, Anita -- nautilus's clever anti-hax0r detection is really dumb https://launchpad.net/bugs/19101 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
