Steps:
1. Attempt to trade gil to a character in exchange for 3 items, and character receiving gil has a full inventory.
2. Even though gil recipient is trading 3 items (and will open 3 slots in their inventory upon trade completion), trade will only succeed if item recipient does not trade gil.

Gil counts as an item.

That's not really a bug. That's just how the trade system works.
