PayPal Error: 10413 Transaction refused because of an invalid argument

[DarrenGriffin]

Setting up my store and am getting the following error on checkout:

10413 Transaction refused because of an invalid argument. See additional
error messages for details. - The totals of the cart item amounts do not
match order amounts.

I have logging enabled, sample log file below. Any help on a resolution appreciated:

Have you upgraded to v1.3.9 yet? It includes several fixes for that and related issues.

[DarrenGriffin]

I'd just seen the post announcing the upgrade but was concerned about the need to to re-install all the payment and shipping modules.

However, as it's not working now I guess I need to bite the bullet and upgrade!

I'll do that now and retest.

Hmm I can see this isn't going to be a simple process <sob>

Too easy mate, upgrade to 1.3.9b and the 10413 error is gone.
