Crash in NXOAuth2AccountStore - didFailToGetAccessTokenWithError

I'm getting a crash in NXOAuth2AccountStore, and I'm not sure if there is anything else I can do. Here is the stack trace:

CoreFoundation __exceptionPreprocess + 124

3 CoreFoundation -[__NSDictionaryM removeObjectForKey:] + 688
4 App -[NXOAuth2AccountStore oauthClient:didFailToGetAccessTokenWithError:] (NXOAuth2AccountStore.m:530)
