[XeTeX] polyglossia font warnings -- not sure what they mean

[Youssef Cherem]

Hi everyone,

I've tried to take out bidi/arabxetex and the abnt package (I'm now 
using natbib instead of abnt). The document still compiles fine, but... 
there are still endless warnings of the same kind:
=================================================
Package polyglossia Warning:  brazil at font is not defined on input line XX.
=================================================

and now lots of other ones too:
===================================
! Extra }, or forgotten \endgroup.
\par ...m \@noitemerr {\@@par }\fi \else {\@@par }
                                                  \fi
l.190
     
I've deleted a group-closing symbol because it seems to be
spurious, as in `$x}$'. But perhaps the } is legitimate and
you forgot something else, as in `\hbox{$x}'. In such cases
the way to recover is to insert both the forgotten and the
deleted material, e.g., by typing `I$}'.
======================================

Preamble is much the same as before, see below:

  {\singlespacing%
   \small
   \begin{list}{}{%
       \setlength{\listparindent}{0cm}%
       \setlength{\itemindent}{\listparindent}%
       \setlength{\rightmargin}{0cm}%
       \setlength{\leftmargin}{4cm}%
       \setlength{\parsep}{0pt}}%
    \item\relax}%
  {\end{list}}



\begin{document}...

========================================

Could it be the new environment for citations (citacao) or some /other/ 
incompatibility problem?

Apparently it's not affecting the compiled document, but if it is, I 
can't tell. I'm just worried about so many warnings.

Thanks again,
