Pessoal estou com um problema aparentemente simples.

Comecei um novo Plug-in Project, usando o template Plug-in with an editor.

Quando tento rodar a partir de uma nova instancia do Eclipse, acontece o seguinte erro:

!ENTRY org.eclipse.osgi 4 0 2011-05-04 09:59:43.251
!MESSAGE An error occurred while automatically activating bundle org.eclipse.equinox.app (264).
