@kotakanbe : I used to face the same kind of problem and submitted a PR that you have merged : #135

By now the offending method "NewOvalDB" does not exist any longer in the current base code. I suppose concurrent writes on the ovalMap data structure occurred. As nor the method nor the data structure exist I guess you can close this issue.
