The application crashes in Chromium when specifying i18n setting

[aitzol76]

Describe the bug
The application crashes and doesn't load in Chromium if I specify via the i18n setting eu(basque) as locale and at the same time in the browser that language is not selected as first. In the browser's console I don't get any error message that makes me suspect it.
Here is my config:

converse.initialize({
  authentication: "login",
  theme: "concord",
  domain_placeholder: "user@example.org",
  view_mode: "fullscreen",
  i18n: "eu"
});

To Reproduce

1. Setup explicit locale via i18n, in my case eu
2. Try to open the client in Chromium
3. The page does not load correctly.

Expected behavior
As in other browsers, I expect the application to load correctly.

Environment (please complete the following information):

• Desktop
• Chromium Version 120.0.6099.129 (Official Build) built on Debian 12.4, running on Debian 12.4 (64-bit)
• Converse.js v10.1.6

Additional context
Works fine in Firefox and also Webkit based browsers.
