Please check whether Geithware\DebugMysqlDb\Database\DatabaseConnection instanciates TSFE and if so, it obviously does it wrong.

The call comes from here:

GeneralUtility:

    protected static function instantiateClass($className, $arguments)
    {
    debug ($className, 'instantiateClass $className');
    debug ($arguments, 'instantiateClass $arguments');
        switch (count($arguments)) {
            case 1:
                $instance = new $className();
                break;
            case 2:
                $instance = new $className($arguments[1]);
                break;

$arguments has a value with index 0 and no value with index 1.

Array
0    TYPO3\CMS\Core\Imaging\IconProvider\FontawesomeIconProvider
instantiateClass $arguments

count($arguments) gives '1'. So the first switch-case is called without the parameter.

The previous call comes from line 4514 of GeneralUtility.php:

        // Create new instance and call constructor with parameters
        $instance = static::instantiateClass($finalClassName, func_get_args());

It should have considered that the $argments⁰ is a given parameter.

The hook is started from TYPO3 extension "tslib_fetce":

tslib_fetce/Classes/Hooks/TypoScriptFrontendTceController.php

However it cannot be called at the moment, because the TYPO3 version has been checked:

class TypoScriptFrontendTceController extends \TYPO3\CMS\Frontend\Controller\TypoScriptFrontendController {

....

// Hook for processing data submission to extensions:
if (
    version_compare(TYPO3_version, '7.0.0', '<') &&
    is_array($this->TYPO3_CONF_VARS['SC_OPTIONS']['tslib/class.tslib_fe.php']['checkDataSubmission'])
) {
    foreach ($this->TYPO3_CONF_VARS['SC_OPTIONS']['tslib/class.tslib_fe.php']['checkDataSubmission'] as $_classRef) {
        $_procObj = GeneralUtility::getUserObj($_classRef);
        $_procObj->checkDataSubmission($this);
    }
}
