Weird Get object crash (257.10)

I've been using the Get object without problems for a long time, but now suddenly this simple event crashes my app:

Start of frame
--> Get URL Please login to see this link.

On get complete
+ one action when event loops
--> Set alterable string to Received$("Get")

Crashes every time on my iPhone 5 iOS 6.

I get EXC_BAD_ACCESS errors in 0_cache_getImp, UIApplicationMain, etc.

As usual, I have tested this on other runtimes and within MMF2, and it works normally there.

I will PM an mfa to Anders and Francois, if you have time to take a look what's going on.

Thanks Anders, however no solution yet. I tried cleaning and deleting the derived data. I've rebooted my phone, mac and PC. Tried also with completely new iOS Xcode project and with a new mfa re-created with same events as in my example mfa. Have tested with iPhone 5 iOS 6.0, iPod touch 4th gen iOS 6.0, iPad 1 iOS 5.1.1 and iPhone 6.1 emulator. It's really weird that none of these worked while you had no problems running it on your side.

Below's the Xcode output from my last try. Does it say something to you?
