Dear list,
I have a core-data app which syncs its data over mobile-me via sync services. Every couple of days or so, the app crashes on different machines. The stack trace is pasted below. I'm using essentially the same syncing code I use for other apps and I haven't seen this problem before.
Can anyone provide any hints from the stack trace?
Many thanks,
Martin
