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. -- System Information: Debian Release: 10.3 APT prefers stable-debug APT policy: (570, 'stable-debug'), (570, 'stable'), (550, 'testing-debug'), (550, 'testing'), (530, 'unstable-debug'), (530, 'unstable'), (500, 'stable-updates'), (1, 'experimental-debug'), (1, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 5.4.0-4-amd64 (SMP w/4 CPU cores) Kernel taint flags: TAINT_USER Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8), LANGUAGE=en_GB:en (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: SELinux: enabled - Mode: Permissive - Policy name: default Versions of packages libpango-1.0-0 depends on: ii fontconfig 2.13.1-2 ii libc6 2.30-4 ii libfribidi0 1.0.5-3.1+deb10u1 ii libglib2.0-0 2.64.1-1 ii libharfbuzz0b 2.3.1-1 ii libthai0 0.1.28-2 libpango-1.0-0 recommends no packages. libpango-1.0-0 suggests no packages. -- no debconf information
