nautilus (Hardy Heron x86): files and directories deleting with no permission issues

Thanks for reporting this bug and any supporting documentation. Since this bug has enough information provided for a developer to begin work, I'm going to mark it as confirmed and let them handle it from here. Thanks for taking the time to make Ubuntu better!

thank you for your bug report, what trash icon do you use?

The icon trash at the right bottom corner of the desktop.

so that's the applet and not nautilus, reassigning the bug

the issue is similar to http://bugzilla.gnome.org/show_bug.cgi?id=552102

Ubuntu 8.04 - I open nautilus as root, create a file on my normal user desktop, and then close root's nautilus. As a user, I can edit the file but not save it, as expected. I right-click the file's icon and click "move to the deleted items folder"; it is moved to trash despite me not being the owner. I can open trash and drag the file back onto the user desktop. It is now owned by the user, not root.

I'll check the above in a live 10.04 session later.

10.04 live session results:

Kubuntu 10.04 live session-

Open a terminal, type 'sudo dolphin'. Navigate to /home/ubuntu/Desktop. Create a file, call it 'roottest', put some text in it and save. Close dolphin. The cursor does not return to the terminal until I click in the terminal and press 'return'. Type 'exit'; the terminal closes.

In the Desktop folder there is now a file called 'roottest'. Properties > permissions show it belongs to root for whom it is read/write, its group is root, 'group' and 'other' only have read access. It can be edited but not subsequently saved.

Right-click 'roottest' and move it to trash. Properties > permissions now show it is owned by ubuntu, its group is ubuntu, and it has only read permission for owner, group and other.

Restore it. Now it belongs to root again as read/write, its group is root, group and other have read access only. I.e. it is back like it was before being moved to trash.

Move it to trash again. Again, it is owned by ubuntu, its group is ubuntu, and it is read-only for owner, group and other.

Empty trash. File 'roottest' is deleted.

Ubuntu 10.04 live session-

Open a terminal, type 'sudo nautilus'. Navigate to /home/ubuntu/Desktop. Create a file, call it 'roottest', put some text in it and save. Close nautilus. The prompt does not return to the terminal. Click the close button on the terminal. A message appears; 'Close this terminal? There is a process still running in this terminal. Closing the terminal will kill it.' Click on 'Close terminal'. The terminal closes.

In the Desktop folder there is now a file called 'roottest'. Properties > permissions show it belongs to root for whom it is read/write; 'group' and 'other' only have read access. It can be edited but not subsequently saved.

Right-click 'roottest' and move it to trash. In trash, Properties > permissions show it is still owned by root. Restore it. It is still owned by root. Move it to trash again. It is still owned by root.

Empty trash. File 'roottest' is deleted.
