Bug#958017: libpango-1.0-0: Crash in pango_font_get_hb_font

[Sam Morris]

Package: libpango-1.0-0
Version: 1.44.7-3
Followup-For: Bug #958017
Control: -1 severity minor

After upgrading libpangocairo-1.0-0 to the version in unstable,
pango-view gives some more useful messages:

    (pango-view:303404): GLib-GObject-WARNING **: 13:40:03.869: specified class size for type 'PangoCairoFcFont' is smaller than the parent type's 'PangoFcFont' class size

    (pango-view:303404): GLib-GObject-CRITICAL **: 13:40:03.869: g_type_add_interface_static: assertion 'G_TYPE_IS_INSTANTIATABLE (instance_type)' failed

    (pango-view:303404): GLib-CRITICAL **: 13:40:03.869: g_once_init_leave: assertion 'result != 0' failed

    (pango-view:303404): GLib-GObject-CRITICAL **: 13:40:03.869: g_object_new_valist: assertion 'G_TYPE_IS_OBJECT (object_type)' failed

So I think the crash is caused by the version skew between the
different pango libraries.

After installing libpangoft2-1.0-0 (which pulls in libharfbuzz0b as
well), pango-view and other programs work again.
