Raygun 4 iOS Crashing on identify user

I have been getting an exception occasionally when calling the identify user function. It seems to be affecting even the newest version 2.3.0. I'm testing on latest xCode 8 and iOS 10 I call the identify function after a user logs into my app, I normally can replicate it by logging out, and logging back in and occasionally get an error. I'm using it like below:

        if let user = user{
            let userInfo = RaygunUserInfo(identifier: user.userId)
            userInfo.firstName = user.firstName
            userInfo.fullName = user.firstName + " " + user.lastName
            Raygun.sharedReporter().identifyWithUserInfo(userInfo)
        }

The stacktrace in Raygun has this at the top:

0   libobjc.A.dylib    0x00000001812f9b90 objc_msgSend + 16 
1   MyProject            0x0000000100bcc8ec plcrash_log_writer_set_user_info

Below is the stackTrace I get when its crashing in xCode.

Hello Mitchell

I've tested the new update (2.3.2) and I'm still encountering the crash. It occurs with the same steps as before. Calling setUserInfo twice. Full stack trace below.

Hello Mitchell

Thanks for the fast turn around on a potential fix. Unfortunately I have replicated Richard's crash as well. My stack trace looks very similar.

Hi Mitchell, The new version appears to have fixed the crash. Thanks!
