NSMutableDictionary* newFileDates = [[[NSUserDefaults standardUserDefaults] objectForKey:@"File Dates"] mutableCopy];

if there is not already a "File Dates" in the defaults then you will get nil returned.

[newFileDates setObject:fileDate forKey:albumKey];

This will do nothing with a nil newFileDates.

[[NSUserDefaults standardUserDefaults] setObject:newFileDates forKey:@"File Dates"];

This will crash trying to add a nil object.

Hope your bug is as simple as that
