Gambio 2007 verrechnet sich bei Versandkosten in Fremdwährung (USD)

[Elektrofuzzy]

Hallo Leute,

ich bin hier auf einen Bug gestoßen, der sich wie folgt äußert:
Kunde hat bei uns die Wahl, ob er in USD oder Euro bestellt. Stellt er auf USD um, kommt er in der Bestellabwicklung hier hin:



Auf den ersten Blick erkennbar: Die Summe stimmt nicht. Der Shop zeigt zwar alle Einzel-Beträge richtig an. Aber letztlich rechnet er in der Endsumme mit den Frachtkosten auf Eurobasis (diese betragen bei uns 10,12 Euro). Auf USD-Basis müsste eigentlich 31,53 Dollar rauskommen.
Scheint mir nur ein kleiner Bug, aber ich such mir hier einen Wolf: Wo genau rechnet Gambio 2007 (ist noch sehr nah am ursprünglichen xt:c) die Summe aus, die da angezeigt wird?

Heißer Kandidat in meinen Augen ist /shop/includes/modules/order_total/ot_shipping.php

Da wäre der Quelltext folgender:

Kann jemand helfen? Ich bin für jeden Tipp dankbar.
