Sorry, this is fixed in Bullseye already. I was reading the versions too quickly. My fault. Still, the problem is not present in Sid.

Bug#996006: ghemical: Segmentation fault when starting
Dear Maintainer, I could reproduce this inside a minimal qemu VM. Below [1] is a backtrace one instruction before the crash. It looks like this "font" object has the create_hb_font function pointer never initialized. It also crashes with LANG=C set. Unfortunately to me it is not certain if this is an issue with pango or the application. Additionally it looks like there were some changes in pango (e.g. [2]) between the versions of bullseye and buster. In the latter no such crash is observable. Kind regards, Bernhard [1] (rr) reverse-stepi 0x7fb5b32b8c33 in pango_font_get_hb_font (font=font@entry=0x558dd5dcdb30) at ../pango/fonts.c:1928 1928 priv->hb_font = PANGO_FONT_GET_CLASS (font)->create_hb_font (font); 1: x/i $pc => 0x7fb5b32b8c33 : call *0xc0(%r12) (rr) bt #0 0x7fb5b32b8c33 in pango_font_get_hb_font (font=font@entry=0x558dd5dcdb30) at ../pango/fonts.c:1928 #1 0x7fb5b32d4e13 in pango_font_get_hb_font_for_context (context=0x7ffc5f4f04c0, font=0x558dd5dcdb30) at ../pango/pangofc-shape.c:277 #2 pango_hb_shape (font=0x558dd5dcdb30, item_text=item_text@entry=0x7fb5b32dff4e "Zwölf Boxkämpfer jagen Viktor quer über den großen Sylter Deich.", item_length=item_length@entry=68, analysis=analysis@entry=0x7ffc5f4f0850, glyphs=glyphs@entry=0x558dd5acc6c0, paragraph_text=paragraph_text@entry=0x7fb5b32dff4e "Zwölf Boxkämpfer jagen Viktor quer über den großen Sylter Deich.", paragraph_length=68) at ../pango/pangofc-shape.c:345 #3 0x7fb5b32d466f in pango_shape_with_flags (item_text=0x7fb5b32dff4e "Zwölf Boxkämpfer jagen Viktor quer über den großen Sylter Deich.", item_length=, paragraph_text=, paragraph_length=68, analysis=0x7ffc5f4f0850, glyphs=0x558dd5acc6c0, flags=PANGO_SHAPE_NONE) at ../pango/shape.c:205 #4 0x7fb5b32d4adb in pango_shape_full (item_text=, item_length=, paragraph_text=, paragraph_length=, analysis=analysis@entry=0x7ffc5f4f0850, glyphs=glyphs@entry=0x558dd5acc6c0) at ../pango/shape.c:96 #5 0x7fb5b32d4af0 in pango_shape (text=, length=, analysis=analysis@entry=0x7ffc5f4f0850, glyphs=glyphs@entry=0x558dd5acc6c0) at ../pango/shape.c:63 #6 0x7fb5b264b273 in itemize_string_foreach (font=font@entry=0x558dd5dcdb30, language=language@entry=0x0, str=, func=func@entry=0x7fb5b264b010 , data=data@entry=0x7ffc5f4f08f0) at pangox.c:777 #7 0x7fb5b264b9b4 in get_font_metrics_from_string (metrics=0xd60e1730, str=, language=0x0, font=0x558dd5dcdb30) at pangox.c:922 #8 pango_x_font_get_metrics (font=0x558dd5dcdb30, language=0x0) at pangox.c:984 #9 0x558dd55f4556 in pangofont_wcl::ogl_InitPangoFont(char const*) (this=0x558dd5c19bc0, fs=0x558dd5623360 "courier 12") at pangofont_wcl.cpp:79 #10 0x558dd55f492a in oglview_wcl::InitGL() (this=0x558dd5c19bc0) at oglview_wcl.cpp:929 #11 0x7fb5b2c3eebe in base_wcl::LinkWnd(base_wnd*) (this=0x558dd5c19bc0, w=0x558dd5c18fa0) at base_wcl.cpp:111 #12 0x558dd55eb93d in project::AddGraphicsClient(custom_camera*, bool) (this=this@entry=0x558dd5a83df0, cam=0x558dd5c8fae0, cam@entry=0x0, detached=detached@entry=false) at project.cpp:622 #13 0x558dd561dc12 in gtk_project::DoSafeStart() (this=0x558dd5a83df0) at gtk_project.cpp:80 #14 0x558dd561aed3 in gtk_app::gtk_app() (this=0x558dd59fde70) at gtk_app.cpp:450 #15 0x558dd561b165 in gtk_app::GetAppX() () at gtk_app.cpp:465 #16 0x558dd55d49d4 in main(int, char**) (argc=, argv=) at gtk_main.cpp:116 (rr) x/1xg $r12+0xc0 0x558dd60e1e70: 0x [2] https://gitlab.gnome.org/GNOME/pango/-/commit/b5634799586ed8e3496ffc237b8d08e6d4e64d67

Package: ghemical Version: 3.0.0-5+b1 Severity: important Dear Maintainer, Starting ghemical in gnome results in a segfault. An xwindow is opened for less than a second and then closes. I see the following in syslog kernel: [ 4311.905429] ghemical[6179]: segfault at 0 ip sp 7ffe739c2328 error 14 in ghemical[5650ebcd+2a000] kernel: [ 4311.905439] Code: Unable to access opcode bytes at RIP 0xffd6.
