I found this thread looking for a solution to this problem as well. However, I didn't want to delete the photos in my camera. I had a level 10 photographer with several valuable photos he wanted to take home with him. So... I tried removing the camera from his inventory. It works every time. Taking the camera out of his inventory and replacing it immediately fixes/works around this glitch. At least it does for me. In fact, my photographer had two cameras in his inventory. It didn't matter which one I took out and put back.
