Answer: 
Sometimes it helps to clean the eclipse workspace - just start eclipse with -clean and the debug buttons work again.
If any of the watch expressions takes too long to evaluate, those mentioned buttons will appear to be grayed out during the evaluation. In such case removing all watch expressions will help.
