App Crashes: EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0)

I get an error shortly after the app is launched - and i can't figure out why?

Some times the app gets the JSON data and sometimes it does not get the JSON data - but it will always crash after few seconds with the following error code:

EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0)
