I've been running into this recently as well, from the gnome-panel process in flashback mode. I suspect the bug affects both flashback and shell, given that it happens inside of libgnome-menu, which appears to be a shared component between the two.

Here is a symbolized backtrace:

Here is the crashing instruction:

(gdb) x/i $pc
=> 0x7f53ebf43570 <g_desktop_app_info_get_is_hidden>:	movzbl 0xc0(%rdi),%eax
(gdb) p/a $rdi
$1 = 0x0

The cause of the segfault is g_desktop_app_info_get_is_hidden being called with a NULL argument. 

This is most likely the same bug as this one in Cinnamon:

https://github.com/linuxmint/Cinnamon/issues/5882

which was fixed in https://github.com/linuxmint/cinnamon-menus/commit/7516e8d138072d167ea93b37a2ffcbcf5b250756.

I do not fully understand that commit, but I can see that it would have prevented the null pointer dereference that happened here. Perhaps that fix could be ported over to GNOME as well?

GNOME is going to shut down bugzilla.gnome.org in favor of gitlab.gnome.org.
As part of that, we are mass-closing older open tickets in bugzilla.gnome.org
which have not seen updates for a longer time (resources are unfortunately
quite limited so not every ticket can get handled).

If you can still reproduce the situation described in this ticket in a recent
and supported software version, then please follow
  https://wiki.gnome.org/GettingInTouch/BugReportingGuidelines
and create a new enhancement request ticket at
  https://gitlab.gnome.org/GNOME/gnome-menus/-/issues/

Thank you for your understanding and your help.
