gdb tells me this is a stack overflow
Thread 1 "atril" received signal SIGSEGV, Segmentation fault.

I also tested with `gtk3-demo` from `gtk-3-examples` package, and there
are no issues - it works fine.
user@debian:~$ cat /etc/gtk-3.0/settings.ini
[Settings]
gtk-theme-name = Materia-dark-compact
I changed this to Orchis-Dark-Compact, still the same.
I removed that file, still the same.
I also updated gtk3 3.24.51-2 => 3.24.51-3, still the same.

it appears that maybe this bug got fixed.
gimp and atril now work without issues on my system, where before they were
crashing for about a year or more.
Closing this, then.
