AzureDiagnostics crashing with System.ArgumentException: An item with the same key has already been added

In a recent deploy of our Cloud Service I'm getting lots of errors in my Application Event Log. Presumably it's a combination of us misconfiguring something in Azure Diagnostics and Azure Diagnostics being unable to deal with it gracefully. But what specifically is misconfigured?

Every 5 minutes I get this:

First Error with Source=AzureDiagnostics 

System.ArgumentException: An item with the same key has already been added.
   at System.Collections.Generic.Dictionary`2.Insert(TKey key, TValue value, Boolean add)
   at ApplicationInsightsExtension.WindowsEventLogPublisher..ctor(ILogger logger, ITelemetryClient client, String logTablesPath, IEnumerable`1 dataSources, ILocalTableReader tableReader, Dictionary`2 configProperties) in x:\bt\725234\repo\src\agent\extensions\AppInsightsExtension\Publishers\WindowsEventLogPublisher.cs:line 59

   at ApplicationInsightsExtension.Program.Main(String[] args) in x:\bt\725234\repo\src\agent\extensions\AppInsightsExtension\Program.cs:line 43

Then Error Source=.NET Runtime

Looks like the problem was in my Diagnostics Configuration > Windows Event Logs. I had both System!* ticked and also System![System[(Level = 1 or Level=2)]]. D'oh.

I still get the odd other error like this, but doesn't seem important.

System.NullReferenceException: Object reference not set to an instance of an object.
   at Microsoft.Azure.Plugins.Diagnostics.dll.RoleInformation.get_IsWorkerRole()
