Hi,

Just an update, I'm trying to find the changeset that introduced this 
modification.

I am doing this by bisect and my current "good" release is the following:

  changeset:   17465:77bec442a35a
  user:        Rik <address@hidden>
  date:        Wed Sep 18 10:32:27 2013 -0700
  summary:     Overhaul stem family of plot functions.

Bisecting is quite cumbersome in this case as I have to install each time in 
order to use
"mkoctfile" and "pkg install" so if anyone is aware of a changeset in the last 
month that
might have caused this problem I'd really appreciate hints.

Marco, I am CC-ing you because I believe this problem might affect your code as 
well, 
could you please test your package with a recent build of Octave development 
sources?
