I can confirm this "bug" (feature?). I installed 7.04 from scratch, and moved my home dir over from my old Ubuntu laptop. When I try to open png files I get the error: " The contents of the file indicate that the file is of type "PNG image". If you open this file, the file might present a security risk to your system."
My "fix" was: $ mv ~/.local/share/applications/mimeinfo.cache ~/.local/share/applications/mimeinfo.cache.backup $ update-mime-database ~/.local/share/mime -- nautilus's clever anti-hax0r detection is really dumb https://bugs.launchpad.net/bugs/19101 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
