I've encountered the same problem as described above on Ubuntu 18.04. In my case, the dual-boot is Ubuntu and Windows 10 and 2 NTFS partitions for Windows. Ubuntu is also installed in a different partition (as above).
The steps to reproduce and the workaround are exactly the same and the issue is systematic. Attached, you will find the error message that I am getting when trying to access the bookmarked path to one of the NTFS partitions. ** Attachment added: "ErrorMsg.png" https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/1434830/+attachment/5237276/+files/ErrorMsg.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1434830 Title: Clicking on Files bookmark doesn't open the requested folder but gives error message To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/1434830/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
