In text_to_glyphs in sushi-font-widget.c in gnome-font-viewer 3.34.0, there is a NULL pointer dereference while parsing a TTF font file that lacks a name section (due to a g_strconcat call that returns NULL).
A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
