[LQTracker sharedTracker] causing app to crash

8zXh21iT0T9fWEE

My company has an app that uses Geoloqi. It's been working fine until today. All of a sudden our users are reporting application crashes upon start-up. Debuging this project in xcode produces the following lldb dump/trace.

I've tracked the crash down to the Application didFinishLaunching delegate. In this delegate is the standard Geoloqi 'init' code which creates an anonymous user. Setting a breal-point on the following line and then stepping into/over it producs the below crash:

[[LQTracker sharedTracker] setProfile:LQTrackerProfilePassive];
