Claus,
you still produce this in your valgrind report:
==5472== Invalid read of size 4
==5472== at 0x81396F6: Row::previous(void) const (lyxrow.C:112)

I have looked in text.C. Here's what I have at line 650:
if (IsNewlineChar(c)) {
++vpos;
drawNewline(p, pos);
return;
} else if (IsInsetChar(c)) {
drawInset(p, pos);
line 650 ++vpos;
drawForeignMark(p, orig_x, orig_font);
return;
}
As you can see, I'm not calling Row::previous(void) const at all. What does your
source look like?
