This is observed on Linux(OEL6.5, Ubuntu13.04) only.
Steps to reproduce:
1. Run hello.HelloDialogs, select "Exception Dialog", the dialog displays with a hyperlink "Show Details".
2. Click "Show Details", the expandable content is visible. But the dialog is not resized, the content looks to be truncated. One have to resize the dialog manually to get all content displayed.
This happen only for the first time. Once the dialog is enlarged manually, this size will be kept if the expandable content is shown again.
