One of its sources is its own interface. Is this an error with packet tracer or am I not understanding something?

"show ip protocols" displays all sources of information that "ospf 10" has used at some point or another to build its table. This includes the router itself, displayed as "192.168.64.1" in this particular IOS image or "(this router)" in other IOS images, as well as routers that have been down for hours. The output's fine and helpful, used for its intended purpose. For example, today I was having trouble with a neighbor. "show ip ospf neighbor" simply told me it wasn't a neighbor, "debug ip ospf hello" told me it wasn't sending hellos anymore, but only "show ip protocol" told me when was the last time the neighbor had been talking friendly-like. Each particular command has its uses.
If you say it can learn routes from itself,
why wouldn't the routers other serial interface be added to the router information sources.
