Running any WP_CLI command breaks with qtranslate-xt

Describe the bug
When running any WP_CLI command, qtranslate breaks with this message:

Fatal error: Uncaught TypeError: qtranxf_match_page(): Argument #2 ($url_path) must be of type string, null given, called in /wp-content/plugins/qtranslate-xt/src/utils.php on line 334 and defined in /wp-content/plugins/qtranslate-xt/src/utils.php:262

Proposed Solution
I was able to mute the error by bailing early if WP_CLI is defined:

function qtranxf_init_language(): void {
    global $q_config, $pagenow;

    if (defined('WP_CLI')) return;

    qtranxf_load_config();
    // ...
}

I don't know if this has any downsides, but it worked for me.

@herrvigg did you ever come around to having a look at this?

For the time being, I can use --skip-plugins to exclude qTranslate-XT.

Instead of this:

wp transient delete --all

I have to do this:

wp --skip-plugins="qtranslate-xt" transient delete --all

But it would be very nice to have it just fixed in qtranslate-xt, as stated above.

[herrvigg]

I don't see how #1387 would solve this.

In qtranxf_get_front_page_config line 24 can you add this?

var_dump($q_config['url_info']);

It seems $q_config['url_info']['wp-path'] is not set (null). The other fields may give some indications.
Could be some special WP installation that is not supported in some script.

I'll post the var dump tomorrow. I'm indeed using a custom directory structure as described in #1387 (comment) (Test 3)

[hirasso]

@herrvigg This is the requested dump:

array(10) {
  ["cookie_front_or_admin_found"]=>
  bool(false)
  ["pagenow"]=>
  string(9) "index.php"
  ["REQUEST_METHOD"]=>
  string(3) "GET"
  ["scheme"]=>
  string(4) "http"
  ["host"]=>
  string(0) ""
  ["path"]=>
  bool(false)
  ["path-base"]=>
  string(5) "/core"
  ["doing_front_end"]=>
  bool(true)
  ["language"]=>
  string(2) "de"
  ["set_cookie"]=>
  bool(true)
}

This is the directory structure I'm using:

.
├── content # wp content folder
│  ├── ... 
├── core # wp core folder
│  ├── ... 
├── index.php
└── wp-config.php
