Please describe the problem:
When you delete a file or a folder which can't be moved to trash, a confirmation
dialog box.
If you click cancel and retry to delete the file, the confirmation dialog box
doesn't popup anymore and nothing happen.

Steps to reproduce:
1. Create a partition where you only have write access on a specific directory
(Trash can't be created on this partition)
2. On this partition try to delete a folder or a file you have write access.
3. Click cancel button
4. Try again


Actual results:
The dialog box doesn't popup anymore

Expected results:
The dialog box should popup everytime.

Does this happen every time?
yes

Other information:
The bug happens because nautilus thinks the selection has been deleted even if I
canceled the deletion.

in fm-directory-view.c:

static void
trash_or_delete_selected_files (FMDirectoryView *view)
{
        GList *selection;

	/* This might be rapidly called multiple times for the same selection
	 * when using keybindings. So we remember if the current selection
	 * was already removed (but the view doesn't know about it yet).
	 */
	if (!view->details->selection_was_removed) {
		selection = fm_directory_view_get_selection_for_file_transfer (view);
		trash_or_delete_files (view, selection);					 
		nautilus_file_list_free (selection);
		view->details->selection_was_removed = TRUE;
	}
}

view->details->selection_was_removed is set to TRUE even if
trash_or_delete_files didn't succeed because of the cancelation.
