Just did a network upgrade to the official release of 8.10, and had this problem. Any of the directories from 'Places' opened with Totem. From the desktop nautilus launched as normal. I was then able to change 'Open With...' and luckily changing just one folder fixed them all.
Also, possibly related[?] is that the folder icons used in 'Places' are the default Gnome icons, and do not match my icon theme. Before upgrading they matched, but are now different. All other icons in 'Places' are the same, including 'Home' and 'Desktop'. -- opening a directory using an application change associations incorrectly https://bugs.launchpad.net/bugs/260492 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
