Comment 11 for bug 580221

This is not really a bug, but rather a change in the behavior of the "Show directory sizes" command. Previously it would calculate the sizes of all directories in the current directory if no selection was made, otherwise the size of the selected directories.

Now if the cursor is positioned on a file it will do nothing, on a directory --- calculate the size of the highlighted directory, in case if some directories were selected --- the size of these directories and if it's on "..", the size of the current tree.

Whether this is more intuitive or not is debatable, I will try to discuss this behavioral change with upstream.
