I am not sure if this is the good place to post this.
There is a problem with bullets in LyX 1.2.1 when using babel:
If I use the LyX dialog to redefine the bullets, LyX will add this kind of
commands to the preamble
\AtBeginDocument{
\renewcommand{\labelitemii}{\(\circ\)}
\renewcommand{\labelitemiii}{\Pisymbol{psy}{168}}
\renewcommand{\labelitemiv}{\(\diamond\)}
}
But if I use a foreign language (actually french) LyX will add the following
\usepackage{babel}
AFTER the \AtBeginDocument statement, and babel redefine the \labelitem, so
your redefinition is useless, it should be placed after the use package
babel.
Another problem that will occur when this one is solved is that babel
redefine the default, for example LyX assume that \bullet is the default
for \labelitemi, and so doesn't redefine it if you choose \bullet, but in
french the default is a dash, so if I select the \bullet LyX won't create a
\renewcommand which would have been necessarry here.
