You open your mailbox and pickup parcel. When you try and examine it game crashes. This crash is very similar to bug 2879785.
2879785 is actually the letter that refers to this parcel.

This is the very same bug as 2879785. Some items (like the letter and the parcel) are handled in a special way which is broken at the moment.
I am closing this bug as duplicate.
