TestFlight TFLog exception crashing my app

I have a strange problem with TestFlight SDK. On iPhone5 I get this exception, app crashed.

Here is backtrace:

Reason: -[__NSArrayM length]: unrecognized selector sent to instance 0x20c76d80

)

I suggest that code which cause this exception is next:

NSString *urlString = [NSString stringWithFormat:BASE_URL, [[KFLocalDataManager sharedManager] serverName]];
urlString = [[urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding] stringByAppendingString:methodName];
NSURL *url = [NSURL URLWithString:urlString];
TTLog(@"Request URL - '%@'", url);

Where TTLog is 

#define TTLog(__FORMAT__, ...) TFLog((@"%s [Line %d] " __FORMAT__), __PRETTY_FUNCTION__, __LINE__, ##__VA_ARGS__);

url string is url to server like this:

https://xxxxxx.xxxxxxx.com/xxxxx_xxxx/xxxx

This error occurs not every time but always in this place. I have several crash but I cannot see some similar environment for all same crash issues. Also this code running in not main app thread and sometimes in iOS background.

Maybe TFLog have some restrictions for incoming parameters or somebody receive same or similar exception with TestFlight?

I work at TestFlight on the SDK. @Nevir is correct. Unfortunately, TFLog is not thread safe. This issue has been recently brought to our attention. I'm working on an update that will fix this issue and hope to have a beta out soon. I'll keep you updated.

There is a new beta that fixes this issue: 1.3.0-beta. Get it here: https://testflightapp.com/sdk/download/ (look for "Feeling Adventurous?")
