The vertical split bar is still exist even when DIRECTORY_ONLY option is given for JFileChooser in GTKLookAndFeel.
I have attached the snapshot(TemporaryFileLocation2.jpg) check the red box in the image ,which should not be there when DIRECTORY_ONLY option is used with JfileChooser.

Jdk-Info:
---------

Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-beta3-b57)^M
Java HotSpot(TM) Client VM (build 1.5.0-beta3-b57, mixed mode, sharing)

Steps to reproduce:
-------------------

Compare the image and JFileChooser ,drag the vertical split bar which is displayed at the end of the split pane the user able to drag but nothing happens,the user should not see the vertical split bar when DIRECTPRY_ONLY option is used.
