Description Michael Clay CLA 2010-10-01 15:16:14 EDT 
steps to reproduce:

1. open two files of the same language with enabled OutlinePage
2. close them with CTRL+W or CTRL+SHIFT+W

the reason for this exception is the single OutlineWithEditorLinker instance (per language) within LinkWithEditorOutlineContribution.
