I assume that the point I raised below is potientally a very annoying bug.
Could someone who knows this code better check if that is the case?

I fixed that one yesterday (and backported the fix to the stable branch).
Thanks.

  2 - the check

                if ([self lockDefaultsFile: &wasLocked] == NO)
                   {
                        return NO;
                   }

      in NSUserDefaults.m around line 1610
      returns NO, and forgets to unlock _lock.  This will later
      lead to problems with locking.  However still your stacktrace
      does not seem consistent with this option.   But still
      this warrants some investigation! (I think this is a bug.)
