GADBanner error Stack Trace

It seems that I have a new error in my App update. This is a stack trace from Flurry Analytics. Any ideas what this means?

So the App is crashing by something the AdMob SDK does by itself?

iOS App Crash with pthread_kill

I have the following crash report but I can't figure out the cause of this crash. This crash appears quite frequently but the pattern varies at each time. Many thanks!

I am assuming that you download some information from the web and are trying to create a string with some parts of that information:
6 CoreFoundation 0x00000001866bc2bc _CFStringCreateWithFormatAndArgumentsAux2 + 272
7 Foundation 0x0000000187502448 -[NSPlaceholderString initWithFormat:locale:arguments:] + 172
Where ever you are using information that you fetched from the Internet, you should first check if that information is valid and respects the right format you expect. Therefore, I recommend you to validate the information before using it.
this might help you:
iPhone app crash at [NSString stringWithFormat]
the error line must be:
[NSString stringWithFormat:#"%#,%#...",a,b...];

What's the root cause of the this crash in iOS?

After I use flurry to collect the crash reports in my app, I found a lot of crash like this:
