[Bug 452049] Re: Gnome Places contains filesystems mounted via bind

[Lanoxx]

This surprises me, because I am under 12.04 and do see this bug, its
actually present since several years.

The problem lies in the code of glib. Nautilus actually has some code in
place to differentiate between bind mounted mount points and other mount
points. But glib (gio) is not properly handling this case, so the check
in nautilus is never reached.

Title:
  Gnome Places contains filesystems mounted via bind

Status in The "G" Library - GLib:
  Confirmed
Status in Nautilus:
  New
Status in “glib2.0” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: nautilus

  What happens:
  1. mount a folder a to point b with the -bind option in /etc/fstab, for example:
       /media/data	    /home/username/MyDocuments none	bind,user=username,group=username		0	0
  2. reboot and then open nautilus
  3. nautilus will show the new mount point in the places sidebar but it will give you an error if you click on the mount point:
      Unable to mount MyDocuments
      mount: according to mtab, /media/data is already mounted on /home/username/MyDocuments
  mount failed

  What should happen:
  1. nautilus should not show these binded folders since they are well accessible through the filesystem
  2. if the mounted folder (e.g. /mount/data) is a block device then it will appear in the places sidebar anyway and thus it is not necessary to show the mount point again
  3. if the mounted folder is a normal folder from an existing file system then its accessible both from the original location and the newly binded location, thus the is no need to show it in places again
  4. this is quite annoying

  Additional Information:
  This bug persists in Lucid
