System.OverflowException: Arithmetic operation resulted in an overflow.

What steps will reproduce the problem?
1. Created a test project with a test class and two test methods using MbUnit 
3.1.
2. Executing the tests using gallio.echo.exe produces the correct test results: 
Two test methods working correctly; tests succeeded.
3.Executing the tests using Icarus test runner, an exception is thrown.

What is the expected output? What do you see instead?
The two test methods should succeed. No further messages, even less an error 
message :->

Both methods _do_ succeed. But additionally we get an exception in the Icarus 
test runner:
"Unhandled exception: An exception occurred in an event handler."

Please provide any additional information below.

This is the class we created:

    <Testfixture()> _
    Public Class Test
        Dim cnn As SqlConnection
        Dim cmd As SqlCommand
        Dim DS As DataSet
        Dim DR As DataRow
        Dim RecCount
        Dim dt As New DataTable

        Public Sub New()
            cnn = New SqlConnection
            cnn.ConnectionString = "<valid connection string>"
            cnn.Open()

            cmd = New SqlCommand()
            cmd.CommandText = "Exec <valid procedure name> '01.04.2009', '30.04.2010'"
            cmd.Connection = cnn

            Dim da As New SqlDataAdapter(cmd)
            da.SelectCommand = cmd

            da.Fill(dt)
            RecCount = dt.Rows.Count
            DR = dt.Rows(0)
        End Sub

        <Test()> _
        Public Sub CheckTable()
            Assert.AreEqual(RecCount, 200)
        End Sub

        <Test()> _
        Public Sub CheckColSumme()
            Assert.AreEqual(DR.Item("Summe").ToString, "250000.0000")
        End Sub

    End Class
