I'm not sure why I missed this when we were looking into it on IRC, but this is apparently something involving the openssl and nss crypto libraries / frameworks. I'm not enough of a developer to understand what exactly seems to be the problem, though, but knowing that apache httpd supports HTTPS with not just openssl I'd check which of these modules are enabled, and maybe make sure only one of them is used temporarily while you check whether you can still reproduce. I.e. look for 'ssl' (openssl) and something 'nss'-like in /etc/apache2/modes-enabled/ and maybe try disabling or re-enabling one of those.
I also think you should still try to
sudo apport-collect 1854395
after reproducing this segfault.
