This bug started when I upgraded my development machine.

The fix is stupid...but the problem went away...Simply wrap it in a try catch block. I had it in a property.

Never seen it again.

Private Function MyMasterPage() As SalesMasterPage
    Try
        Return CType(Page.Master, SalesMasterPage)
    Catch ex As Exception
        'log error
    End Try
End Function

If you have a masterpage called femaster_master try to exclude this one from the project you should be able to see where it is (incorrectly) referenced.
