Did you try enabling the exception breakpoint? You can try tracking that zombie on instruments, the long way:

  1. Run your app on Intruments.

  2. In instruments, select Object allocations tool(automatically selected if you select leaks tool).

  3. Click on the little "i" on top left, within the Allocations tool.

  4. Select "Enable NSZombie detection".

  5. Press the record button and let your app run.

  6. Go through the execution of the app untill it crashes. As soon as there is a crash, you'd see a pop up saying that there was a EXC_BAD_ACCESS. Click on the little -> on the pop up to see the object that has turned into a zombie and the line of code responsible.
