Hi again,
with the attached ("heuristic") patch I fixed this problem, which was
arising when searching for stuff inside a math environment nested inside
a table cell (i.e., searching for a+b inside Math.lyx). In such
segments, I'm assuming the direction is Left To Right (but don't
actually know if in those countries maths are also left-to-right, or if
they are heels under kneels).

Hi all,
could anyone please explain what is the purpose of the "- 2", in this
method (from InsetTabular.cpp) ?
5090 bool InsetTabular::isRightToLeft(Cursor & cur) const
5091 {
5092 LASSERT(cur.depth() > 1, /**/);
5093 Paragraph const & parentpar = cur[cur.depth() -
2].paragraph();
5094 pos_type const parentpos = cur[cur.depth() - 2].pos();
5095 return parentpar.getFontSettings(buffer().params(),
5096 parentpos).language()->rightToLeft();
5097 }
I get a stdlib assertion when trying to put the cursor at
inset: 0x3378a60 idx: 0 par: 82 pos: 0
inset: 0x34cdf60 idx: 4 par: 0 pos: 10
in Math.lyx (I frozed a version of this file at
http://feanor.sssup.it/~tommaso/Math.lyx), and the troublesome line is
the 5093, inside the paragraph() method (despite the LASSERT()). Full
backtrace follows. AFAICS, the cursor position where I'm trying to
move is legal.
Thanks, bye,
T.
