When I try to run my iOS app through the Leaks instrument in the simulator, very shortly after launch, without fail, it will stop with the error "An error occurred trying to capture Leaks data"


All the disclosure says is "Error retrieving leak information." I can't find any other information. Checking the console view, it just shows a normal run up until "<End of Run>"


I've tried doing a clean build, deleting my derived data, uninstalling the app from the simulator, restarting Xcode, rebooting. I have no idea what to do.
