Hi! I recognize this is a very old thread, but wanted to ask whether this issue was ever resolved. My G1 is having the exact same issue - it will only fire the shutter without film in the camera. The issue started after I used the double exposure mode for the first time and I'm wondering if it may have messed up the film advance mechanism. I'm seeing references to this exact issue with G1s all over the internet, but no solutions yet. Hope it got resolved for you. Thanks!
