Move to next state moves orders two states

Actually using 6.x-3.2+0-dev.

I initially opened this as an Ubercart core issue #1540392: Order automatically moved to completed, skipping payment received but as I gather more info from the store admins, it seems this is probably a UC Views or a VBO issue.

Creating a new issue here rather than moving that one because there's a lot of unnecessary cruft in that one.

Basically, orders come in and they are marked as Payment Received. When the guys start processing orders, they print out packing lists using a bulk op, and then move the orders to Processing using a bulk op. In a small number of cases, the orders then get moved two seconds later to Completed.

We started noticing this around mid-March.

1. When they move an order to Processing, it's usually (almost always) done bulk using Views Bulk Operations Ubercart Views.

2. When they move an order to Completed, it is always done from the individual order screen on an order by order basis.

When I looked at the raw log entries in the database to get a little more granularity on the timestamp, I found two orders that had this happen. They both were moved from Payment Received to Processing and I think everyone agrees this was an intentional operation by the admin.

But then two seconds later, they both got moved to Completed.

Here are the log entries. Two comments
- these are all the status changes for these two orders with the important ones bolded
- these are all the status changes for all orders during that period for the store

1334774285, 3101, 0, Order status changed from In checkout to Pending
1334774292, 3101, 0, Order status changed from Pending to Payment received
1334775226, 3102, 0, Order status changed from In checkout to Pending
1334775229, 3102, 0, Order status changed from Pending to Payment received
1334776830, 3101, 25, Order status changed from Payment received to Processing
1334776830, 3102, 25, Order status changed from Payment received to Processing
1334776832, 3101, 25, Order status changed from Processing to Completed
1334776832, 3102, 25, Order status changed from Processing to Completed

Any ideas?
