Order Line Totals Causing Strange (but repeatable) Crashing

[Dealec]

I can replicate the problem on the test site Sellerdeck has when you first install it, but i've also found that it's not always a line total problem.

When testing the £347.30 line total the order doesn't crash until you add £8.75 shipping (our standard charge for items over 10kg) which suggests the crash also happens when any of the order value boxes reach a certain value.

Have to say this is a very strange problem.

The only time I've sen anything like this in the past has been when orders include details of a shipping charge that doesn't exist.

There isn't anything about these orders that would break the shipping calculations is there? Or any other kind of order related charges / details / discounts etc?

We have been experiencing certain orders crashing Sellerdeck, and we couldn't figure out what made these orders different from others until yesterday.

The pattern in problem orders seems to be the line total, i'll give an example below:

If you have a product costing £72.56 (any price between £72.53 and £72.57 inclusive also work), and start a new order (works with both orders placed online, and offline although offline is a quicker way of testing). When you try to place the item into the basket Sellerdeck will crash and you'll have to reload.

If you run the order through the website you'll find you can download the order, but not open it.

If you then change the price to £72.58 and try again it doesn't crash and lets you add the item.

This works even if multiples of the product add up to the magic number (more I've found listed below), so having 2 x £36.28 will also cause the crash.

I've tested this on both our current running site, and a completely fresh site, but it would be great if others could also test this out.

Values I've found so far are:

£72.56
£104.55
£1041.90
£347.30
