A user added a Japanese site link and the edit summary says "Added link to [enwiki]: Liancourt Rocks" (instead of jawiki ...) http://www.wikidata.org/w/index.php?title=Q20317&diff=next&oldid=61046611
I will add https://gerrit.wikimedia.org/r/#/c/75338/ to this. the above change is reworking most of the api modules to use changeops instead of the current system. Summaries will be handled in a totally different way and this bug will likely be fixed as a result.
Report with an example and reopen if this still occurs.
