I think there are two slightly related problems at work here.  One of
them is that Gmail disconnects after we send NUL characters so we can't
move the message and we throw a backtrace.

Another is that once this happens *once* for some message, then it's no
longer possible to `B m' even other normal messages.  It seems that when
Gmail drops the connection Gnus gets 'stuck' trying to recover from the
dropped connection, or trying to use the connection that is no longer
available.
