That's one minor problem. Another problem I've experienced as well as heard about was the part where the door hinges/connects. There is a thin loophole of plastic through which a metal pin passes. A spring around the pin pushes the door away from the camera body. If one of the plastic loops (one top, one bottom) snaps you can still keep the door shut with some ease, however if both snap (as mine currently have, one then the other some time later) you will need the action grip and a bit of electrical tape.

Well, any tape will do, really... but the electrical is black and tacky enough to hold but soft enough to peel away when you need to get the battery in or out. Just about the right tape for the job!
