the message tells you that you are using NS* objects without an 
Autorelease Pool. It will cause issues, but "should work", so your app 
should run.
I notice what they appear to be CoreFoundation bridge object. You should 
try to track where they come from, maybe put a breakpoint and stacktrace.

The snipped seen in the commit looks trivial, no nsblocks needed and has 
an fresh ARP allocated, so I think the issue is elsewhere.
