Facebook sign in issue - applicationStart getting called randomly

Guys I have this odd problem, if I use facebook.login to login to the browser version of facebook (native app not installed), if I have already allowed the app all of the authroisations it needs then when I get sent back into the app the state either goes to applicationResume, which is fine but sometimes randomly goes to applicationOpen then applicationStart so the app boots from scratch and achieves nothing.  This is iOS 6.1 btw.

Application exit on suspend is false in my build settings and like I say sometimes it returns to the app OK and sometimes not.  Using build 1202 and tried 1179 but they are the same.

Any ideas?
