ShareKit Crash on Facebook direct sharing

I'm using ShareKit to share an item to Facebook and Twitter using this code

SHKItem *item = [SHKItem image:imageToShare title:textToShare];

NSLog(@"Sharing to facebook...");

SHKFacebook *fbSharer = [SHKFacebook shareItem:item];

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(showAnotherViewController) name:@"SHKSendDidFinish" object:fbSharer];

Everything works like a charm apart from iPhone 5, where the app crashes. This is the crash report generated:

I cannot replicate the crash, it doesn't happen on my iphone 5s nor on the simulator

** EDIT ** Further investigations help me detect the error. It's not the iphone 5 the problem. I Have the crash on this method

-[FBSession reauthorizeWithPermissions:isRead:behavior:defaultAudience:completionHandler:]

and it happens with every other Facebook account (except for mine). Of course i remembered to allow Facebook app access to general public.
