Is this reproducible if you disable the extension? Did you get this extension from Debian or from extensions.gnome.org? If an extension is causing a crash, there is usually not much that gnome-shell can do about it. Extensions work by "monkey-patching" the gnome-shell code, and have just as much control over execution as gnome-shell does. > Nov 17 17:42:40 krikkit gnome-shell[2918]: ../../../gobject/gsignal.c:2732: > instance '0x55db198ddf00' has no handler with id '10990' This suggests that something (presumably the vertical overview extension) is not keeping track of its signal handler IDs correctly. > Nov 17 17:42:40 krikkit kernel: gnome-shell[2918]: segfault at 55de45d1f627 ip > 00007f39f4900b29 sp 00007ffd73fdd360 error 4 in > libst-1.0.so[7f39f48de000+4b000] Can you get a backtrace from this crash? systemd-coredump is usually the easiest way to achieve this.
