Luckily, not so hard to fix.  See cset http://hg.savannah.gnu.org/hgweb/octave/rev/adf580507691.  Fixed, closing report.

Confirmed.  It also affects the development version.  The problem seems to be that property/value pairs are processed in the order in which they appear.  In this case, the "string" property of the object is set first, which provokes an error, and then the "interpreter" property is set to "none".

This should be fixed so that the "string" property is set last, after any other properties which may affect its display such as "fontname", "fontsize", "interpreter", etc.

As a workaround, you can do that yourself.  This example shows how.

ht = title ("");
set (ht, "interpreter", "none", "string", "a_");

I am getting an error (status?) message printed when it shouldn't in the following:

filename = 'aFileWithEndUnderscore_';

The console shows the following: 'TeX parse error: syntax error'. It doesn't show as an actual error that stops execution, but shouldn't be displayed when 'interpreter' is set to 'none', indicating that TeX parsing isn't wanted.
