Notice: A non well formed numeric value encountered when choosing "other amount" on contribution page using non-US settings
Notice: A non well formed numeric value encountered in CRM_Price_BAO_LineItem::format() (line 317 of .../web/sites/all/modules/civicrm/CRM/Price/BAO/LineItem.php).
Haven't looked further yet. Set the settings to non-US money formats and then visit a contribution page and choose other amount and fill it in, e.g.
12,34, then on the next page you get the notice. Everything still works though.
