open type dialog is empty - RSA (Rational Software Architetc) for WebSphere 7.5.0 on Linux (Ubuntu 9.04)

Question

I have a fresh install of RSA 7.5.3 in Linux (Ubuntu 9.04). I've create a new workspace with one Java project. When I open the "open type" dialog I get an empty box - see attached screenshot. You can notice that there is no package specified at the bottom of the dialog. when I try to look for a class I get the following exception:

Error occurred during status handling
java.lang.ArrayIndexOutOfBoundsException: Array index out of range: -1
at org.eclipse.jface.viewers.AbstractTableViewer$VirtualManager.resolveElement
(Unknown Source)!
