AppleEvent: как отлаживать `eventDidFail`?

Я получаю эту ошибку от SIMBL в консоли: 

05.09.11 17:00:09,165 SIMBL Agent: eventDidFail:'tvea' error:Error Domain=NSOSStatusErrorDomain Code=-1708 "The operation couldn’t be completed. (OSStatus error -1708.)" (the AppleEvent was not handled by any handler ) UserInfo=0x400e485c0 {ErrorNumber=-1708} userInfo:{
    ErrorNumber = "-1708";
}

Я пытаюсь отладить это;но поскольку я еще не так много работал с AppleEvent, я не совсем уверен, как это интерпретировать.

Я думаю, что связанный код в агенте SIMBL такой: 

AEEventID eventID = 'load';

// Find the process to target
pid_t pid = [[appInfo objectForKey:@"NSApplicationProcessIdentifier"] intValue];
SBApplication* app = [SBApplication applicationWithProcessIdentifier:pid];
[app setDelegate:self];
if (!app) {
    SIMBLLogNotice(@"Can't find app with pid %d", pid);
    return;
}

// Force AppleScript to initialize in the app, by getting the dictionary
// When initializing, you need to wait for the event reply, otherwise the
// event might get dropped on the floor. This is only seems to happen in 10.5
// but it shouldn't harm anything.
[app setSendMode:kAEWaitReply | kAENeverInteract | kAEDontRecord];
id initReply = [app sendEvent:kASAppleScriptSuite id:kGetAEUT parameters:0];

// the reply here is of some unknown type - it is not an Objective-C object
// as near as I can tell because trying to print it using "%@" or getting its
// class both cause the application to segfault. The pointer value always seems
// to be 0x10000 which is a bit fishy. It does not seem to be an AEDesc struct
// either.
// since we are waiting for a reply, it seems like this object might need to
// be released - but i don't know what it is or how to release it.
// NSLog(@"initReply: %p '%64.64s'", initReply, (char*)initReply);

// Inject!
[app setSendMode:kAENoReply | kAENeverInteract | kAEDontRecord];
id injectReply = [app sendEvent:'SIMe' id:eventID parameters:0];
if (injectReply != nil) {
    SIMBLLogNotice(@"unexpected injectReply: %@", injectReply);
}

Сообщение eventDidFail также поступает от самого агента SIMBL. Вот этот код: 

- (void) eventDidFail:(const AppleEvent*)event withError:(NSError*)error
{
    NSDictionary* userInfo = [error userInfo];
    NSNumber* errorNumber = [userInfo objectForKey:@"ErrorNumber"];

    // this error seems more common on Leopard
    if (errorNumber && [errorNumber intValue] == errAEEventNotHandled) {
        SIMBLLogDebug(@"eventDidFail:'%4.4s' error:%@ userInfo:%@", (char*)&(event->descriptorType), error, [error userInfo]);
    }
    else {
        SIMBLLogNotice(@"eventDidFail:'%4.4s' error:%@ userInfo:%@", (char*)&(event->descriptorType), error, [error userInfo]);
    }
}

И ошибка исчезнет, ​​если я закомментирую этот код: 

[app setSendMode:kAEWaitReply | kAENeverInteract | kAEDontRecord];
id initReply = [app sendEvent:kASAppleScriptSuite id:kGetAEUT parameters:0];
...
