The following assertion is triggered in text2.C:994 (LyXText::editXY()):

    // This should be just before or just behind the
    // cursor position set above.
    BOOST_ASSERT((pos != 0 && inset == pars_[pit].getInset(pos - 1))
             || inset == pars_[pit].getInset(pos));


The problem is that at pit=13 and pos-1=317 we have
  inset != pars_[pit].getInset(pos - 1)

Anybody understand the problem?

I still see this crash, the attach patch will reveal that 
inset2=inset3=0. If this normal?

pit 24  pos -1 332
inset 022C6250
inset2 00000000
pit 24  pos 333
inset 022C6250
inset3 00000000
