Hi, Clark,
as it was me who made initial statement I post here just to clear the question.
In any case please do not consider this as unfriendly. We really appriciate your greate service.
As I already reported to you similar issues it is also interesting for me what is the thechnical problem and solution for this.
Please tell your opinion.
I happen to have captured the MtGox trade stream at that point in time... maybe that helps (note that time is shown as 04:39 due to timezone stuff, also note that this data is filtered by price_currency == 'USD'). It seems to have been exactly one trade, amount 1700 BTC, no other trade happened on that minute (04:39)

also note: I think that first timestamp in each line is my system time. The trades unix time is: 1353728373, which translates to "2012-11-24 04:39:33"
EDIT: I also just checked: the trade with that id (1353728373761573) only appears once in my dataset (ranging from 2012/11/23-11:19:06 to 2012/11/24-12:52:10). Also no other trade of volume 1700 BTC appears in my data.
