Nextcloud IOS App crashes when opening svg image created using Mermaid Live Editor

Steps to reproduce

1. Upload SVG to Nextcloud server (I created an SVG using the Mermaid Live Editor)
2. Open the file on Nextcloud IOS

Expected behaviour

Either the image opens, is downloaded to the device, or is shown an error.

Actual behaviour

App crashes instead of opening file

Logs

Server log containing relevant info:
{"reqId":"203FizwzUiCut2ciifNj","level":0,"time":"October 04, 2022 13:40:15","remoteAddr":"<redacted>","user":"<redacted>","app":"core","method":"GET","url":"/index.php/avatar/<username_but_redacted>/256","message":"Avatar requested in deprecated size 256","userAgent":"Nextcloud/4.4.4 (it.twsweb.Nextcloud; build:0; iOS 16.0.0) Alamofire/5.6.2","version":"24.0.1.1"}

Reasoning or why should it be changed/implemented?

App breaks when performing what normal user would think is a simple action.

Environment data

iOS version: iOS 16.0.0

Nextcloud iOS app version: 4.4.4.0

Server operating system: Debian, running via Docker

Web server: nginx

Database: mariadb 10.5

PHP version: 8.0.18

Reproduce the crash by uploading a Mermaid Live Editor SVG to the Nextcloud server and opening it in the iOS app using the reported versions. Start by examining the iOS client’s crash output; the supplied server log does not identify the failing code path. Done means the SVG opens, downloads, or produces an error without crashing.
