Do not assert if an inset separator is the only item of a List
environment. Although it is a weird thing to do, both GUI and
latex output can deal with it.
Paragraph const & par = text_->getPar(pit);
pos_type last = par.beginOfBody();
- LBUFERR(last > 0);
+ LBUFERR(last > 0 || par.isEnvSeparator(0));
// -1 because a label ends with a space that is in the label
--last;
// a separator at this end does not count
- if (par.isLineSeparator(last))
+ if (last >= 0 && par.isLineSeparator(last))
--last;
int w = 0;
