Please describe the problem:
It is not possible to remove a symbolic link to a folder or file on an other filesystem for instance a symbolic link ~/Desktop/linkToFile pointing to a file on /media/hda5/file cannot be removed even though it is possible to do so by opening a terminal and type "rm linkToFile"

Steps to reproduce:
Assume you have two partitions /dev/hda1 and /dev/hda5, /dev/hda1 is the root filesystem and /dev/hda5 is mounted as /media/hda5. /media/hda5 is mounted with "users,owner,rw,exec" so it is possible for the current user to create, move and delete files and folders.
1. Greate a folder named "test" on /media/hda5
2. Create a symbolic link from ~/Desktop/newLink to /media/hda5/test/
3. Try and delete the link


Actual results:
You will be prompt by a dialog box saying "Error 'Not on same filesystem' when deleting '~/Desktop/newLink'"(translated) and asks you to try again or cance


Expected results:
The link should be deleted

Does this happen every time?
yes

Other information:
Work fine opening a terminal and typing "rm newLink"
