You did not commit yet, didn't you?
No, not yet.
Somehow I am getting strange crashes while scrolling wit the mouse.
Here the backtrace of the first 12 levels:

Can someone make sense out of it?
The crash may be dependent on preferences, because I could not make it
crash on fresh
userdir.
It certainly looks like you must have "cursor follows scrollbar" set. Is
that the difference from the fresh userdir?
In any event, the assertion is here:
void Text::setCursor(CursorSlice & cur, pit_type par, pos_type pos)
{
LASSERT(par != int(paragraphs().size()), /**/);
cur.pit() = par;
cur.pos() = pos;
I'm not sure why we are making exactly this check.
