Anyone have experience freeing an SD card that is stuck in the GH1's card slot? I inserted an SD card with its write-protect tab engaged and it appears to play back properly in the camera. The push-activated card eject mechanism inside the camera is working as usual, however, the card hits some kind of block about a third of the way out when I pull on it. The blocked area feels like it's on the lower edge of the card. I can return it for warranty service, but would prefer to fix it myself if possible.
