GANTracker V1.4

Happens intermittently on iOS5.0.1 on the 3GS.

When the application goes into the background and GANTracker calls stopTracker 
then stopTimer, and invalid selector message is sent to another component in 
the app.

-[ClassName invalidate]: unrecognized selector sent to instance 0x6cfc20

After more testing, this also happens intermittently on the iPhone4 running 
iOS4.3 and on the iPhone4S running iOS5.0.1.

Trigger when application goes into background by the GANTracker stopTimer call. 
 Is anyone else seeing similar behavior?

yes, I'm seeing the exact same behavior. fixed it by adding an empty stopTimer 
function in a separate category for GANTracker, and I consider it lucky not to 
see any memory leaks because of it.

Yep, I see this as well. I'm only stopping the tracker when the app terminates, 
so I guess I can just let the singleton get dumped...

I'm also getting the same error and have "solved" as has bogdan.c.  I hope 
Google can give us a proper solution as overriding compiled code with no idea 
what this is affecting is certainly not a solution at all.

Mine is very similar.  I think it is this:
