gtk_text_view_get_iter_location() always returns rect.y == rect.height
rather than the correct value, as demonstrated by this test program:

Upstream considered this is not a bug, here's the response:
------- Additional Comment #2 From Matthias Clasen 2003-12-27 17:35
-------
This is probably the result of working on an unrealized text view,
though I can't explain exactly where the y =3D=3D 17 originates. Moving
the get_iter_location() call into the callback makes your testcase=20
report=20
x =3D 202, y =3D 136
w =3D 7, h =3D 17
I'm closing the two Debian bugs. Feel free to resubmit or better
reopen if you consider this is insufficient.
