NullPointer Exception when Attempting to Link a Knowledgebase

Reproduce:

We upgrade to Confluence 5.8.6. Then went into Service Desk and selected a project. We choose Settings->Confluence KB->Link to a Knowledge Base and Select Confluence in the drop down.

When the attempt to select as space the following error occurs:
