The GtkDisplayState *s struct is enormous but gdb seems to be able to print all of it. gtk3-3.22.6-2.fc25.x86_64 Hmm, let's try updating that. Fails in the same way with gtk3-3.22.8-2.fc26 Fix upstream in git master with

ui/gtk: fix crash at startup when no console is available
This patch fixes a segfault at QEMU startup, introduced in a08156321ab9a7d2fed9ee77dbfeea2a61ffd153.
gd_vc_find_current() return NULL, which is dereferenced without checking it.
While at it, disable the whole 'View' menu if no console exists.
Reproducer: qemu-system-i386 -M none -nodefaults

As far as I can tell this doesn't affect upstream qemu. The stack trace is: Thread 1 "qemu-system-x86" received signal SIGSEGV, Segmentation fault. 0x0000555555acc49c in gtk_display_init (ds=<optimized out>, full_screen=<optimized out>, grab_on_hover=<optimized out>) at /usr/src/debug/qemu-2.8.0/ui/gtk.c:2253 2253 gtk_widget_set_sensitive(s->copy_item, (gdb) bt #0 0x0000555555acc49c in gtk_display_init (ds=<optimized out>, full_screen=<optimized out>, grab_on_hover=<optimized out>) at /usr/src/debug/qemu-2.8.0/ui/gtk.c:2253 #1 0x0000555555816b33 in main (argc=<optimized out>, argv=<optimized out>, envp=<optimized out>) at /usr/src/debug/qemu-2.8.0/vl.c:4615 Version-Release number of selected component (if applicable): qemu-2.8.0-2.fc26.x86_64 How reproducible: 100% Steps to Reproduce: 1.
