That seems reasonable. But, when you're trying to figure out why the
dissector is calling the packet bad, it's sometimes helpful to know why
it's bad. (Diameter is a new protocol, undergoing heavy development).
What about a preferences setting, something like "Verbose Error
Messages" that would output g_warnings() everywhere for warnings. (And,
it would otherwise be quiet)
