NSMetadataQuery is being deallocated without first calling -stopQuery.

I am trying to get iCloud document load/save working between an iOS and OS X app. It seems to work OK, but on the Mac side, I see this message whenever I save or load a file:


<NSMetadataQuery: 0x6100000e2a80> is being deallocated without first calling -stopQuery. To avoid race conditions, you should first invoke -stopQuery on self.operationQueue.


Anyone know what that means? How do I fix it? I'm not doing any kind of data query myself, it must be something being done automatically behind the scenes.


Thanks!
