Bug#857290: Alternatetab makes gnome-shell segfault when window closes while switching

Pietro Battiston me at pietrobattiston.it

Package: gnome-shell-extensions
Version: 3.22.2-1
Severity: important

I use Alternatetab, and gnome-shell segfaults every time I switch away from a
window and the window closes before I finish switching (or in other terms:
every time I send an email with Evolution and forget to wait before switching
away from the composer window).

This didn't happen until some versions of gnome-shell ago (but I am unable to
provide more precise estimates of the regression version).

To reproduce:
- start gnome-shell
- enable Alternatetab
- open two terminals
- in one run "sleep 3; exit"
- before 3 seconds, press Alt+Tab to switch to the other, but leave Alt
pressed, and wait

I am attaching the backtrace.
