Bagas, I know you are trying to help, but sorry, I'd say this is not
helpful at all -- any maybe even harmful.

>From the quoted texts it's pretty clear that the reporter knows that a
bisection would be helpful, but currently is unable to perform one --
and even states reasons for reporting it without having it bisected. So
your message afaics doesn't bring anything new to the table; and I might
be wrong with that, but I fear some people in a situation like this
might even be offended by a reply like that, as it states something
already obvious.

Ciao, Thorsten
