Notes
The error exists since at least 1.34-wmf.3, possibly earlier.
It looks like the the MediaInfoByLinkedTitleLookup class provided by WikibaseMediaInfo is forgetting to validate a title somewhere prior to use, causing this null value to sneak through and causing a fatal error when later code assumes it to be a valid Title object.
