Event registrations total amounts with decimals stored incorrectly when CiviCRM thousands separator is a dot

This occurs only if CiviCRM is set with thousands separator as a dot, a normal configuration in spanish and catalan installations.

When a total amount for an event contains a decimal value and we submit the registration, then the amount is stored incorrectly in the database. For example:

If the total amount is 150.50 then is stored as 1505 in the entity_financial_trxn table.

I inspect as far I know and I found that the problem comes from the cleanMoney function in CRM/Utils/Rule.php, specifically the following lines:

// ugly fix for CRM-6391: do not drop the thousand separator if
// it looks like it’s separating decimal part (because a given
// value undergoes a second cleanMoney() call, for example)

if ($mon_thousands_sep != '.' or substr($value, -3, 1) != '.')

{ $value = str_replace($mon_thousands_sep, '', $value); }

The input value of $value at the entry of this lines is 105.5 and the output value is 1505.

The backtrace to this point is

CRM/Event/Form/Participant.php >
1045: CRM_Price_BAO_PriceSet::processAmount($this->_values['fee'],
CRM/Price/BAO/PriceSet.php >
785: CRM_Price_BAO_LineItem::format($id, $params, $field, $lineItem);
CRM/Price/BAO/LineItem.php >
260: $price = CRM_Utils_Rule::cleanMoney($price);

From there I no longer dared to change anything for fear it may affect other functionalities of the CiviCRM.

Someone may end up giving a push to fix the bug?
