No messages shown in endpoint with messages from external source

This seems to be related to the issue fixed in ServiceControl :
ServiceControl stops shortly after starting #427

The fix seems to work in ServiceControl and it now shows the correct info in ServicePulse. But when we try open the message from external source (i.e. Biztalk) in ServiceInsight, it refuses to list any messages in endpoints containing these external source messages:

If I browse the url to serviceControl API manually in Chrome for example I get a list of messages back. I think the problem lies within the ServiceInsight-client trying to display a list of messages in the gridcomponent, try to parse the external source messages and crashes, resulting in no messages shown in grid for that particular endpoint.
