Using KDE 4.0.85.
When one navigates the directory tree by clicking folders in details or icons view, the corresponding folders in folders panel do not expand themselves automatically. Also, once this is done, it's not possible to expand the folder in folders panel manually neither. This do not happen when navigating using the columns view.

To reproduce:
1. Expand your home directory in folders panel and select it
2. In details view, double-click any directory which has more subdirectories inside (say, Documents). Notice that the Documents folder in folder panel do not automatically expand, although you have entered this directory in details view
3. In details view, double-click any subdirectory of the first one (say, "text documents"). Notice that the Documents folder in folder panel do not automatically expand, although you have just entered one of its subdirectories
4. Now try to expand the first directory (Documents) manually in folder panel, clicking on the plus sign next to it. Notice that the plus sign turns into a minus, but the folder will not expand. Now it's necessary to close and reopen Dolphin to get this folder to expand.

The same happens using icons view, but not using columns view.
