Are you sure that you recive this error after this lines of code? Use this code to be quite sure that your program have/not have errors in this part of code:

NSLog((@"%s [Line %d] "), __PRETTY_FUNCTION__, __LINE__);
NSData *thumbnailData = UIImageJPEGRepresentation(place.thumbnail, 0.8);
NSLog((@"%s [Line %d] "), __PRETTY_FUNCTION__, __LINE__);
placeDict setObject:thumbnailData forKey:thumbnail];
NSLog((@"%s [Line %d] "), __PRETTY_FUNCTION__, __LINE__);

Yes, I'm sure, I commented this line and it was OK without it. But error occurs when I'm running [placesToPack messagePack]. – Shmidt Dec 11 '12 at 11:29
And what is placesToPack? In your code there is only placeDict. – Mikhail Viceman Dec 11 '12 at 11:31
array, containing placeDict. – Shmidt Dec 11 '12 at 11:36
