A particular client may or may not show the problem.  If the client is
constant, either the problem exists all the time or it doesn't.

However, the text in the subject line matters.  Because Mailman
changes the subject field (adding the list prefix), it may have to
refold the header field.  But this isn't always true.  So sometimes
the problem shows up, sometimes not, even with the same client.
