I'm not doing this on purpose, but my images are a wide variety of
stuff.

My image has all text removed and only noise :-)

Why not accept that some images might really have some very high and
very small characters? Its not that unlikely, e.g. with advertisements:
"free beer coupon *" in huge characters, and "* not valid in
Lampukistan" in very small characters. If you make a real change,
there's always the risk that you'd get worse results for the majority of
images while solving a problem that almost never happens. Maybe a
solution would be that if there are no medium characters, to just add
one element that produces a space...

On the other hand, I just thought of another "symptom" fix, and it
works: at the end of Textblock::Textblock(), replace 

tlpv[i]->insert_spaces();

with

if (tlpv[i]->height() > 0)
  tlpv[i]->insert_spaces();
