I have the following weird error; An exception thrown on the empty Catch block!

Any ideas how this is possible and how to fix it?

Thanks!

Ok, i think i got it...

For Each mediaPlayerID In _attachedDevices.Values.GroupBy(Function(t)t.MediaPlayerInfo.ID).Distinct()
    Try
        fileSystemPerMediaPlayerId.Add(mediaPlayerID.Key, New FileSystemOnDevice())
    Catch
    End Try
Next

The problem is caused by a null variable in the lambda expression inside the GroupBy method...
The compiler just pointed the wrong line..

It tried and failed, but there was nothing in the catch to handle it, hence the error NullReferenceException was unhandled.
