One of my internal doors slowly swings fully open unless it's latched

something to do with how it's hung, but I can't find any obvious
problems. It's a solid hardwood door (so pretty heavy) hung on two
brass hinges.

A spirit level shows that the door frame on the hinge side is
vertical, and the hinge side of the door is vertical as well. A plumb
bob made from a nut&bolt on a piece of string shows that the two
hinges are in line vertically.

Any ideas on what could be causing this?

the hinges not being inline. Result: the door drops fractionally as it opens.
