We're occasionally seeing crashes within our app using the latest ArcGIS SDK.
It's a EXC_CRASH (SIGSEGV) on thread 0, but no code is running on thread 0 at the time (at least in the crash report).
The common theme with all of the crash reports we're getting is a call to [AGSLocalTiledLayer batchTilesRequestOperationSucceeded:]

I've attached the full crash report. Does anyone have any ideas?
