Botan assert error crashing server

[WebFreak001]

source/app.d:

import vibe.d;

shared static this()
{
	auto settings = new HTTPServerSettings;
	settings.port = 8080;
	settings.bindAddresses = ["::1", "127.0.0.1"];
	settings.tlsContext = createTLSContext(TLSContextKind.server);
	settings.tlsContext.useCertificateChainFile("testing.crt");
	settings.tlsContext.usePrivateKeyFile("testing.key");

	auto router = new URLRouter;
	router.get("*", serveStaticFiles("./public"));

	listenHTTP(settings, router);
}

dub.json:

{
	"dependencies": {
		"vibe-d": "~>0.8.1",
		"vibe-d:tls": "*"
	},
	"versions": [
		"VibeDefaultMain"
	],
	"subConfigurations": {
		"vibe-d:tls": "botan"
	},
	"name": "test-app"
}

Generate local test keys script:

#!/bin/bash
NAME=${1:-testing}

openssl req \
  -newkey rsa:4096 \
  -days 1001 \
  -nodes \
  -x509 \
  -subj "/C=US/ST=California/L=San Francisco/O=Twitch/OU=web/CN=localhost" \
  -extensions SAN \
  -config <( cat $( [[ "Darwin" = "$(uname -s)" ]]  && echo /System/Library/OpenSSL/openssl.cnf || echo /etc/ssl/openssl.cnf  ) \
    <(printf "[SAN]\nsubjectAltName='DNS:localhost'")) \
  -keyout "${NAME}.key" \
  -out "${NAME}.crt"

echo ""
echo "Generated $NAME.key and $NAME.crt files in local directory"
echo ""

if [[ "$OSTYPE" == "darwin"* ]]; then
  echo "Installing cert into local Keychain."
  echo "To see or modify, run 'Keychain Access' app and look in the 'System' Folder"
  sudo security add-trusted-cert -d -p ssl -r trustRoot -k "/Library/Keychains/System.keychain" "${NAME}.crt"
else
  echo "Please install and trust cert at $PWD/$NAME.crt"
fi

Generate the keys using that shell script, run the server and try accessing https://127.0.0.1:8080/ - the server will crash with this exception:

Happened to me with a client request (requestHTTP("https://...")) as well:
