The code for font metrics had some serious bugs. Just today Keith
Packard committed a big rework of this code. Please give it a try and
see if it doesn't behave any better for you.

There's an example in CVS in cairo-demo/png/text.c:

	http://cvs.cairographics.org/cairo-demo/png/text.c?view=markup

And its output can be seen here:

Oh, look at that. The extents definitely look much better, but now the
results of cairo_show_text are not matching cairo_text_path followed
by cairo_stroke. That's a new bug, as can be seen by comparing with
the old output (with the buggy extents):
