Game Center causing app crash - ios

My app is crashing when Game Center is logged in, all is fine through the simulator and in sandbox mode on all devices. I have had some negative feedback regarding the crashes so have started to look through it. I thought it was solved so got the update out, but I was wrong.
I have this crash report from my phone but am some what baffled.

iOS app crashed in thread wihtout app actions

My iOS application crashed. In crash log I've found such info:

I have no idea how to interpret this. There are some additional actions happening in other thread but they looks ok. Any idea why thread which does nothing crashed?

I'm using the ExternalAccessory framework which I've had problems with in the past and the App crashed whilst receiving data from a bluetooth connected external device. However, I can't tell if that was what caused the crash.
Thanks in advance.
The crash was caused by something that went wrong inside of:
[UIKeyboardTaskQueue waitUntilAllTasksAreFinished]
which was called in the process of executing:
[UISearchBar setText:]
So, it seems, you typed something in a search bar, and the app crashed.

ios app crashes for only one customer

One of my customers reports consistent crashing, about 75% of the times he performs a particular operation in the app. That operation involves some image processing. He's using an iPhone 4S (the same model I used when developing the app) and iOS 7.1.1. No other customer has reported this issue. He has deleted the app and reinstalled from the App Store. He's using the app's default settings. I cannot recreate the issue.
Thread 8 crashes, but does not show any lines in my code ("gCard"). The issue appears to be "doesNotRecognizeSelector:" in a thread that does not show any lines in my code. I don't understand this. (The app uses brad Larson's GPUImage but I don't know if that's a factor.)
I need help to understand the dump and suggestions on my next step.

Your app crashes while a UILabel inside a UIScrollView inside an alert is deallocated. I'd suspect that either your app overwrites memory somewhere and this is just a symptom, or you are using some alert in a non-standard way, possibly changing a paragraph style somewhere in the alert in a way that's wrong.
First step would be to turn all reasonable warnings on in the compiler, use the static analyser to find problems, and fix all of them.

Deciphering a Crash Report - iOS - xCode

I am trying to replicate a bug in my app which is happening for users occasionally. I have the below crash report. Am I right in thinking the app is crashing due to an NSDictionary not having a value for a specific key ? And is there anything else I can deduce from the report ?

Code which is crashing :
- (void)_sendData:(NSDictionary *)data responseCallback:(WVJBResponseCallback)responseCallback handlerName:(NSString*)handlerName {
NSMutableDictionary* message = [NSMutableDictionary dictionaryWithObject:data forKey:#"data"];
if (responseCallback) {
NSString* callbackId = [NSString stringWithFormat:#"objc_cb_%ld", ++_uniqueId];
_responseCallbacks[callbackId] = [responseCallback copy];
message[#"callbackId"] = callbackId;
}
if (handlerName) {
message[#"handlerName"] = handlerName;
}
[self _queueMessage:message];
}
The crash happens in the file WebViewJavascriptBridge.m in line 95 in the method [WebViewJavascriptBridge _sendData:responseCallback:handlerName:].
That line causes an exception in [__NSPlaceholderDictionary initWithObjects:forKeys:count:]. Since the exception message isn't shown in the crash report, and you don't provide any source code of that place we can only assume what is happening.
One assumption would be, your are creating a dictionary with nil values or keys. But without code or you actually debugging this, this is only an assumption.
