-----------------------+--------------------------------
 pango 1.30.1 has a coretext bug that can cause the errors below.

 The current MacPorts pango version seems to be 1.30.1 which probably
 contains the coretext bug.

 ---------------------------------------------------------------------

  GLib-GObject-CRITICAL **: g_object_ref: assertion `G_IS_OBJECT (object)'

 GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)'

 Pango-CRITICAL **: _pango_cairo_font_map_get_renderer: assertion
 `PANGO_IS_CAIRO_FONT_MAP (fontmap)' failed

 -----------------------------------------------------------------------------------

 pango 1.30.0 doesn't have the coretext bug and is ok.

 The bug was introduced with pango 1.30.1 and fixed in a later version

 Introduced bug from pango 1.30.1 ChangeLog

     Bug 673497 - corefont fallback not always working

     The fallback failed when a "small caps" font was requested. This
     commit
     improves the fallback support. When the first fallback, trying
     Sans with
     the same style fails, we reset the variant, weight and stretch to
     default values and try again. With Sans we should always be able to
     adhere to the requested style.

     Last but not least, output a sensible error message if all fallbacks
     fail instead of simply crashing on a NULL pointer somewhere.

 and fixed in the pango later than 1.30.1 ChangeLog

     coretext: don't insert item in the hash if it originated from the hash

     Oversight in my fallback fix, this resulted in things being wrongly
     destroyed due to unrefs. Oops.
