Help solving iPhone app crash - iphone

Question

I released an update to one of my apps recently. This update made some small changes to the data structure, which is causing problems for some people. I have got a hold of some crash reports and narrowed it down to the line in question, but for the life of me can't see anything wrong with it. I'm not able to replicate the problem at my end either, which doesn't help.
The section of code is:
-(void)performV160Upgrade {
for(id key in self.consumptionHistory) {
Consumption* consumption = [self.consumptionHistory objectForKey:key];
for(Entry* entry in consumption.entries) {
if(!entry.emotionDescription || [entry.emotionDescription isEqualToString:#""]) {
if(self.emotionDescriptionDefaults && [self.emotionDescriptionDefaults count] >= entry.emotion) {
entry.emotionDescription = [self.emotionDescriptionDefaults objectAtIndex:entry.emotion-1];
}
}
}
}
NSUserDefaults* defaults = [NSUserDefaults standardUserDefaults];
[defaults setBool:YES forKey:#"V160Upgrade"];
[defaults synchronize];
[self saveDataFile];
}
Specifically, the crash occurs on the innermost if statement, when assigning entry.emotionDescription (this is line 251). For some context, consumptionHistory is an NSMutableDictionary, consumption.entries is an NSMutableArray, self.emotionDescriptionDefaults is an NSMutableArray of NSString's, and entry.emotionDescription is an NSString.
I'll attach the crash log below. Any ideas or suggestions on where to go to from here would be greatly appreciated!

Answer 1

im not sure what entry.emotion is, but i assume its an integer (since you are using it as an index, and subtracting one from it)? if so, you are probably causing an index out of bounds error by trying to access an index in your array that does not exist (-1 for instance)
