Ошибка GAIUncaughtExceptionHandler только для iOS 7

Попытка раздавить один из наших более постоянных отчетов о сбоях. Подозрительно, потому что это исключительно iOS 7. *, неясно, что такое триггер, и это относительно небольшой процент наших пользователей, столкнувшихся с проблемой. Чувствует себя как состояние гонки или iOS 7. * конкретная ошибка с SDK Google Analytics. Мои взаимодействия с SDK прямолинейны:

+ (void)trackEvent:(NSString *)category action:(NSString *)action label:(NSString *)label value:(NSNumber *)value
{
    // May return nil if a tracker has not already been initialized with a
    // property ID.
    id tracker = [[GAI sharedInstance] defaultTracker];

    [tracker send:[[GAIDictionaryBuilder createEventWithCategory:category
                                                          action:action
                                                           label:label
                                                           value:value] build]];
}


+ (void)trackScreenView:(NSString *)screenName
{
    // https://developers.google.com/analytics/devguides/collection/ios/v3/screens

    // May return nil if a tracker has not already been initialized with a
    // property ID.
    id tracker = [[GAI sharedInstance] defaultTracker];

    // This screen name value will remain set on the tracker and sent with
    // hits until it is set to a new value or to nil.
    [tracker set:kGAIScreenName
           value:screenName];

    // Previous V3 SDK versions
    // [tracker send:[[GAIDictionaryBuilder createAppView] build]];

    // New SDK versions
    [self visuallyLogTrackingDetails:tracker dictionaryBuilder:[GAIDictionaryBuilder createScreenView]];
}

Также есть случаи, когда я передаю больше данных на вызов (помимо имени экрана), например:

+ (void)trackGenderedScreenView:(MyAppGender)gender
{
    id tracker = [[GAI sharedInstance] defaultTracker];

    [tracker set:kGAIScreenName
           value:MyAppAnalyticsGenderedScreenName];

    GAIDictionaryBuilder *dictionaryBuilder = [GAIDictionaryBuilder createScreenView];
    [dictionaryBuilder set:[MyAppUtil getGenderedString:gender]
                    forKey:[GAIFields customDimensionForIndex:ASPAnalyticsDimensionGender]];

    [self visuallyLogTrackingDetails:tracker dictionaryBuilder:dictionaryBuilder];
}

Версия SDK: службы Google Analytics iOS 3.10

Влияние: ограничено iOS 7. *.
