+<P>When copying, rather than moving, a file into the trash (i.e. When
+trashing to the &ldquo;home trash&rdquo; from a different partition),
+exact preservation of permissions might be impossible. Notably, a
+file.directory that was owned by another user will now be owned by
+this user (changing owners is usually only available to root). This
+should not cause the trashing operation to fail.</P>
+<P>In this same situation, setting the permissions should be done
+<I>after</I> writing the copied file, as they may may make it
+unwriteable..</P>
+<P>A trashing operation might be refused because of insufficient
+permissions, even when the user does have the right to delete a file
+or directory. This may happen when the user has the right to delete a
+file/directory, but not to read it (or, in the case of a directory,
+to list it). In this case, the best solution is probably to warn the

+alone.</P>
+<P>Automatic trash cleaning may, and probably eventually should, be

+<P>If a directory was trashed in its entirety, it is easiest to
+undelete it or remove it from the trash only in its entirety as well,
