I can reproduce this easily with zsh 3.0.6 or 3.1.6 on FreeBSD (2.2.6
and 4.0).  The TERM variable has to be set to a 'dumb'-style terminal,
or blank.  I thought I could reproduce it on Solaris 2.6 but it doesn't
seem to be cooperating right now.

% zsh -f
% PROMPT="%m %n %/ %%"
dan dan /home/dan % TERM=dumb
dan dan /home/dan % 
                    ^ blanks start here and don't stop

Oddly enough, "%m%n%/" doesn't trigger the bug. "%m  %n" does. "%m %n"
does not.

Termcap entry for 'dumb':
