Retested this. The problem doesn't occur on 12.10 or 13.04. It still happens on 12.04.2, which is using with nautilus 3.4.2.
Actually 12.10 is also using nautilus 3.4.2. So maybe this isn't a nautilus bug after all. In 12.04.2 the window pops up but nothing changes in the Unity bar. In 12.10, there is a drive icon for the partition being mounted which disappears when I mount it on /mnt. and reappears when I unmount it. So... now I'm thinking this is actually a Unity bug in 12.04.2. ** Package changed: nautilus (Ubuntu) => unity (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/986269 Title: Unable to open a folder for 10 GB Filesystem", "No application is registered as handling this file... or Nautilus pops browser when partition is mounted in bash script To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity/+bug/986269/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
