Happened to me as well. I charged both of my k-5 batteries -- grip and camera -- last week. I usually charge just one, and then get the other next time. I left each of them on the charger for a couple of hours after they were fully charged. Right after charging the second battery, I tried to use the camera, I experienced the mirror-flop disorder. At least that's what I assume it was. The camera kept making a clicking noise when the shutter was pushed and wouldn't function. I switched off the trip, and the camera started working intermittently, so I turned on preview and left it on for a few minutes. After that it worked fin, and I was able to switch the grip back on. I'm going to go back to charging only one battery at a time and taking care not to overcharge. Or if I do charge both at once, which I have to do for big jobs, I'm going to make sure they don' t spend too much time on the charger, and I'm going to leave the grip turned off until I've logged a few shots.
