I would conjecture that it has to do with the fact that you do not have
write permission in /home!  The backslashed version just creates
homemean_monthly_stl.eps in the current directory. If you substitute
/tmp for /home, the problem goes away (provided you're on some kind of
Unix/Linux -- you didn't say). It's still a bug of course.
