The un-named service, has stopped working with the unspecified version 
of Pidgin, running on an un-named operating system, when attempting to 
connect through an unknown sort of network connection, and no debug log 
information has been provided.

What has changed since it worked?

The first message doesn't appear to exist in Pidgin 2.7.10 - it may have 
come directly from the service, or may have been mis-copied.  The second 
message can only be produced by Pidgin when accessing the MSN service.

There have been many reports of the second problem, but I've not heard 
of a developer being able to reproduce it.

Emails are not formal business letters, whatever businesses may want.
RFC1855 says there should be an address here, but, in a world of spam,
that is no longer good advice, as archive address hiding may not work.
